Peek Inside Gravity

In the future, only one rule will matter: Don’t. Ever. Peek. Ari Alexander just broke that rule and saw the last person she expected hovering above her bed —arrogant Jackson Locke. Jackson issues a challenge: help him, or everyone on Earth will die. Giving Jackson the information he needs will betray her father and her country, but keeping silent will start a war.

In the future, only one rule will matter:

Don’t. Ever. Peek.

Seventeen-year-old Ari Alexander just broke that rule and saw the last person she expected hovering above her bed—arrogant Jackson Locke, the most popular boy in her school. She expects instant execution or some kind of freak alien punishment, but instead, Jackson issues a challenge: help him, or everyone on Earth will die.

Ari knows she should report him, but everything about Jackson makes her question what she’s been taught about his kind. And against her instincts, she’s falling for him. But Ari isn’t just any girl, and Jackson wants more than her attention. She’s a military legacy who’s been trained by her father and exposed to war strategies and societal information no one can know—especially an alien spy, like Jackson. Giving Jackson the information he needs will betray her father and her country, but keeping silent will start a war.

NOTE: I read the early arc version - not the finished arc.

I was never really into aliens (until I read Obsidian!) and then I became quite obsessed with them. When I came across Gravity during it's cover reveal, I thought it was the perfect book. I mean helloooooo, have you seen the cover? The summar ...more

Gravity was such an addicting read! I finished the book in one day, two sittings. When I picked it up at my bookstore I thought it sounded intriguing and noticed it had a gorgeous cover, with a praising quote from Jennifer L. Armentrout I might add. Basically, I had high expectations and they were m ...more

It may sound cliche, but GRAVITY is one of those special books that hooks you from the first page and just doesn't let you go.

The only world that Ari Alexander has ever known, is one in which humans are forced to play host to the Ancients. This alien race has such a powerful and frightening control ...more

This was such a great alien book; I’m now actively searching for more to read. After the awesomeness that was the incredibly popular Lux series (Hi Daemon!), I was a little nervous about reading Gravity because no matter how much you want to enjoy a book if it’s similar to another series that you lo ...more

Okay, so I was really excited when I first saw this absolutely gorgeous cover, and when I read the synopsis I couldn't wait to get my hands on it! That "Dont. Ever. Peek." gave me the chills!!!

Gravity literally made me feel like I was floating; it made me lose my breath at certain points, and had me squealing like a love-struck girl. Everything from the out-of-this-world plot to the witty dialogue was able to hook my interest. It had me ADDICTED. I ...more

I got Gravity as an offer. One of those days when Amazon randomly decides to lower book prices and the Kindle edition of this one was literally 1€ so I just had to buy it. I didn't know if I would like it but it sounded cool and gave it a try. Expectations met!

GRAVITY is like summer box office action movie packed inside a beautiful blue book!

I loved this book! To be honest I've never really read much in the sci-fi genre, but after reading GRAVITY, I'm an official fan.
