A threat from the past could destroy the future. And the clock is ticking... 
 Kaleb Ballard's relentless flirting is interrupted when Jack Landers, the man who tried to murder his father, timeslips in and attacks before disappearing just as quickly. But Kaleb has never before been able to see time travelers, unlike many of his friends associated with the mysterious Hourglass organization. Are Kaleb's powers expanding, or is something very wrong? 
 Then the Hourglass is issued an ultimatum. Either they find Jack and the research he's stolen on the time gene, or time will be altered with devastating results. 
 Now Kaleb, Emerson, Michael, and the other Hourglass recruits have no choice but to use their unusual powers to find Jack. But where do they even start? And when? And even if they succeed, it may not be enough... 
 I really enjoyed this installment in the Hourglass series. When I found out there was going to be a sequel, I was thrilled. However, I was surprised to find out that it was from a different perspective than Emerson's. At first, I thought it was supposed to be from Michael's perspective, and was excited because I would have loved to see things through his eyes. But than I learned it was from Kaleb's, and I'll admit, I was a little disappointed. While I loved Kaleb in Hourglass, I loved Michael more. Nevertheless, there were parts of this book that had me laughing, and falling in love with Kaleb even more (everyone loves a bad boy). 
 The story itself was very intriguing, and exciting. I loved going on the journey, with it's roller coaster up's and down's. Even though the story is from Kaleb's POV, we still get moments of Emerson and Michael. The writing was fantastic, with great descriptions that make the rips come alive (pardon the pun). I do wish there was a little bit more of a recap in the beginning because I had a hard time remembering who and what everyone and everything was, but by about 50 pages in, I fully remembered everything. I guess that this is to be expected when you have books published a year apart, but I really wish authors would start incorporating some type of recap into the beginning chapter. It would save us all a lot of time and trouble than having to go back through the previous book to remember what certain things are (usually I would just reread the book, but if your anything like me, you have no time to do that, and so many other books to read). 
 Be prepared, the ending is a cliffhanger, and will have you eagerly waiting for the next book, Infinityglass. Honestly, I wish I had the travel gene right now, just so I can see what happens next. Was this book as good as Hourglass, no. It does kind of experience that second book syndrome. However, I still highly recommend it to people who loved the first novel, and to people who are looking for an interesting new series, that covers a genre that is not in heavy rotation right now (aka vampires, fairies, and werewolves).
