Guest Review Taken From Book Angel Booktopia 
 BZRK... I'm not 100% sure how to describe this book as this is a ... well... a hard thing to explain. But here's my attempt. BZRK, the first in a new series, is about nanos and biots. Not sure what these are? These are nanobots and biots, the biological counterpart of nanos. And here, it seems the world is in danger from these. Or rather, the group known as AFGC, who want to "rewire" the most powerful minds of the world: the President of the United States and the British Prime Minister, to name two. But BZRK has to stop them. Enter Sadie and Noah, the teenagers with their private reasons to join. But with the stakes so high and failure meaning they might lose their sanity, losing isn't an option... 
 Now, this is my first Michael Grant book (never read his Gone series, though I have been told I should loads of time in the past), I don't know what my reaction would be. And, I hate to say, I'm a bit "muh" over it. I didn't love it, but I didn't hate it. I'm just in the middle, not sure with myself if I like or not. 
 Ok, let's talk about this book's good point. Once you got your head into this, it was a fast thriller that played out on two levels: in real life and in nano (or "down on the meat"). And with technology at the level it is at the present moment, you sometimes go "This could/might be possible..." 
 But, there are problems with this book. The first problem I had was when the story or the action scene jumped for human to nano/biot. For the first half of the book, I sometimes had to reread paragraphs to go "OK. Where am I again?" so I didn't get confused. And near the end of the book, I suddenly started seeing the nanos and the biots like the robot-cookies from Despicable Me. 
 Another problem I had was the characters. I'm sorry, but I want to be gripped by the characters very quickly. I want to read their story and want to rush back to the book because of them. And with these characters... it took a long time to warm to them or the situation. And the reason I feel for this was that I never felt like I had time to get to know the characters. I would have a chapter (at the most) with one character before it jumped to another character, whether they were the good guy or the bad guy. I never "clicked" with any of the characters. 
 I'm still unsure on how I feel about BZRK. This wasn't my cup of tea. But I'm sure all the Gone fans will love this and am sure that some of you guys will enjoy it a lot more than me. So please, don't let me review put you off. If you want to read this book, READ IT!
