Bob vs the Selfie Zombies is such a great book that my boy really enjoyed reading. The cover is very eye-catching and fits the story perfectly. My boy enjoyed reading it on his own practicing his reading as well as I read it for him for bedtime. The characters are all appealing and the story really interesting and kept my boy engaged and interested every time we read it . He found the time travelling fascinating and asked me many questions about it . The zombie part of it he found cool and funny at times . We both quite enjoyed this book and I even read it myself on my own altho it's for the younger audience. I even bought it for my nephew for Easter and he's started reading it straight away and told me it's the coolest book he has ever received. So this book is definitely a good hit with teens as well as with my 6 years old boy . I would be buying it for my friend's boys too to enjoy.
