Flu was one of those indie zombie books that was just decent. Nothing really special but yet very addictive. The only problems I really had were some spelling errors, not enough explanation why and how the flu makes you into a zombie and that basically all the main characters drop dead like flies. Like two main characters survive.. -_- So don't get attached to anyone in this book!
I'll definitely look into getting ahold of the next book. Hopefully we find out some more information on the flu!
