SPOILER ALERT!
I was struggling with this before I put it "on hold" and after reading a few reviews of the book on Goodreads I've realised that as much I quite like zombies books--as long as they feature some romance--that this is quite lacking in that respect as the characters don't end up meeting until near the end.
As I've mentioned in other reviews I read a book for the romance aspect and it seems like this is sadly lacking.
