"The author did an amazing job in her world-building, in crafting such a unique setting and story concept. This story seemed to have it all. It sucked me in so quickly and kept my attention riveted." -Shannon, The Tale Temptress

There is one True World, and then there are the four mirror worlds: fire, water, air, and stone. And each has a magic of its own...

In the Fire World, seventeen-year-old Leah is the illegitimate daughter of one of the realm's most powerful lords. She's hot-blooded - able to communicate with the tempestuous volcano gods. But she has another gift...the ability to Call her twin "Otherselves" on other worlds.

Holly resides in the Water World - our world. When she's called by Leah from the Fire World, she nearly drowns. Suddenly the world Holly thought she knew is filled with secrets, magic...and deadly peril.

For a malevolent force seeks to destroy the mirror worlds. And as Leah and Holly are swept up in the tides of chaos and danger, they have only one choice to save the mirror worlds - to shatter every rule they've ever known...

The Otherselves series is best enjoyed in order.

Through Fire and Sea is a fascinating YA sci-fi/fantasy that begins with Leah, an unrecognized daughter of a hot-blooded duke. The dukes control the volcanoes, making it safe to live on their planet, which is full of fire. Leahs mother had her out of wedlock and tries to keep her away from her fa... ...more

I received this ARC from Entangled Teen in exchange for an honest review.

This was so much more fun than I expected it to be! I'm going to try to describe things without using any spoilers!

In this book, there is the True World, and 4 other worlds. The two worlds present here are Fire, which is rul... ...more

***I received the eBook free as a review copy from the publisher Entangled Teen via Netgalley in exchange for an honest review***

For a very long time Through Fire & Sea was a 3 star book for me, because I lacked any solid emotional investment to the characters, also it was clear from the star... ...more

By Michael (Mai) May 22, 2015

Through Fire & Sea is a really unique look of parallel universes. There are 4 elemental worlds like Fire and Water that the book takes place in and one True World. Someone people have otherselves that exist on these different worlds. Through mirror magic someone people can call their othersel... ...more

When is the next book? When can I see Gideon again? When can we convince Hollywood to make a Violet Eyes movie? Why can't I have my own Otherself?

These are the questions in my mind the second after the last word. Sigh. But really. When can I read about Gideon again?


Heres the thing Ive follow... ...more

NOTE: I was given this book as an ARC by Entangled publishing


This was my first of Luiken's books, although on finishing I discovered that she has previously written other books which I'm sure I'll be exploring soon enough ;)

This book was AWESOME! It mixes high and low fantasy with two st... ...more

By Melissa (YA Book Shelf) March 01, 2016

I really loved Through Fire & Sea. The worlds depicted are complex, including a Water world that very much resembles our current world except with the addition of real, siren magic, and a smaller, but equally complex Fire world, which resembles what the Medieval period have been like had it b... ...more

Actual rating: 4.5 out of 5 stars

I'm still undecided as to who I liked better, Leah or Holly. They're both smart, resourceful and practical, which I instantly loved because I'm tired of the 'badass-but-not-really' kind of female leads. The Otherselves each have their own distinct voice... ...more

Leah is the illigitimate child of a Duke who has always hoped her father would acknowledge her, even if just to get a dowry. Now he has, and not in a good way. He wants Leah to pretend to be his legitimate daughter, so she will get sent away in her place.

This is the start of a binge-worthy series. There isn't just one world, there are several. And the reflections in the mirror, ice, and water connect them all. Within each world, there are a few people able to pass through the reflection to the others. Leah is one of these people, and her ability... ...more

In Nicole Luikens new series the author introduces the YA reader to the concept of mirror worlds, worlds which differ physically but are connected by magical mirrors that allow passage from one to another. Whats more these mirror worlds are populated by mirror people or what the author calls othe... ...more

In this book we begin by following a girl named Leah and her life in a world full of volcanoes and dukes who can talk to them. Leah is the illegitimate child of one of these dukes and is forced by her father to impersonate his real daughter and leave to be an apprentice with a woman called Qetura... ...more

By *Thea July 09, 2015

My Thoughts On The Book:

The Plot Of The Story:
This is an interesting idea for a plot using the thought that there is one 'true' world and four very different 'mirror' worlds and each world is like an alternate reality version of the others.
Leah lives in the 'Fire' mirror world, a world of volcan... ...more

Guys. guys. GUYS. Ive discovered that Im more than just a contemporary girl.

This is an AMAZING book!! Let me tell you how freaking cool this author made this fantastic world! First, there two sets of characters we follow.

In the beginning, there was the True World. It was perfect- so perfect that someone tried to re-create it. First with heat, followed by water, then by stone and finally air. These worlds were not perfect but they were our worlds- our reality. A caller is a person who after looking into a mirror c... ...more

I just finished reading this book last night, so it's fresh on my mind. This was unlike almost anything else I've read in a long time, because it was so very unique. Notice I had a little bit of trouble classifying the genre at the top of the post. It is definitely young adult, but part of the st... ...more

By Elaine May 05, 2015

This is the first book in the Otherselves series. The main background to it is that there are five versions of worlds only one of which is the True World and on each version for some special people there is likely to be someone living there who is that worlds version of them. This story concerns... ...more

This was the first book of the author I've read and I'm glad to say I enjoyed it. It includes the elements but what is unique that it represents the worlds and the true world as well. It also has dragons and merfolk in it. I can't wait to see the other worlds.

The story is kind of dragging but it... ...more

It 's a thrilling fantasy novel with a plot unique, original and intriguing and likeable characters.
The author is very good at mixing fantasy world with the real world. In this story there are four different worlds and the history of their creation is very beautiful and mythological. Our world is... ...more

By Alexa May 03, 2017

As incredible as this story was, it wasnt one of those that took me by the face and drowned me in a sea of epicness from page one. Instead, it was a slow drawing in, a careful engagement of my emotions as I grew to understand the characters and their situations. It subtly pulled me further and fu... ...more
