Fast-moving and punchy, this well-written novel should hold the attention of young teenagers used to the cut and thrust of video gaming. With a clever and exciting plot and strong and endearing characters, this is an Oliver Twist for the 21st century.

The attention to detail is phenomenal - everything has been thoroughly researched from the gadgets, the computer hacking, the undercover surveillance and genetics. All make the reading both fascinating and inspiring. Nevertheless, he has been able to balance this technological combination to create an amazing interactive thriller which is a winner. This is the best fantasy based book that I have read this year; I loved reading every single page.

Rat Runners is a brilliant fast-paced read that delves into some really fascinating issues... All in all, this is a great read for teenagers that will really make them think

This must be Oisín McGann’s best book to date. I have enjoyed all the ones I’ve read, but do feel Rat Runners has that little bit extra... Very exciting, and I am more than ready for the next one. I can’t see that we are done yet.

I thought this book was crime-tastic. It is very adventurous and a really thrilling read . . . one of the best books I have read in my lifetime . . . brilliant with a special storyline.
