Can I just say that I am mind blown before I really get into the nitpicking. This was amazing, and it angered me on many deep levels. I was reading it thinking about time and how in this book it is all happening at once, time just sitting alongside different eras but all coexisting, and I found that fun. Anywho, Nicholas and Etta might just be making it into OTP zone, but I will still lay my claim to have Nicholas as my bff/drinking pal but Etta can have little-sis status. 
 The Actual Review 
 This started off strong, the prologue had me freaking out when Julian died just in the first five pages (it really is not a spoiler), and we're already feeling it with Nicholas. He's a real strong character, with real flaws that I appreciate. Alexandra Bracken makes it very clear he's a man of his time (that being the 18th century) and throughout the book, he catches himself (or Etta gets onto him) underestimating Etta - Why? Because he was raised in a time where women were decoration, not real people. Nicholas is also half black, and Bracken did great at not forgetting that time travel is only fun for the "straight white men." 
 Etta and Nicholas both had some decent character development, though Etta's is by far the most noticeable. Nicholas learned that he doesn't need to just have a ship to be happy, he's looking toward less materialistic things, while Etta who started out as a "Plane Jane" ended up being pretty kickass. She was also shown in her ignorance of what Nicholas grew up in, but overall, she did lack a lot of flaws. Etta was described as near perfect, her only fault was being naive, which isn't even that real of a flaw - What I mean by real, is that she isn't so bad that anyone would blame her. She's just optimistic and doesn't know anything about the world she's been thrust into - She has no flaws, and that did bother me. 
 To wrap it up, the ending was good, and I won't put any spoilers, but it had my mind racing. 
 Okay, now I'm putting in spoilers 
 (view spoiler)[ THIS INFURIATED ME - I THOUGHT ETTA WAS DEAD AND THEN WAS JUST LOSING MY SHIT, AND BRACKEN JUST RUBBED IT IN MY FACE BY SHOWING ME HOW RUINED JULIAN WAS AND THEN - IT'S OKAY BECAUSE SHE'S JUST LOST IN A WRINKLE OF TIME?!?! WHAT. 
 NO NO NO 
 WHAT?! 
 I'm not mad, it was brilliant, that just made me freak way the hell out. (hide spoiler)]
