This is a fabulous series for boys, but this is the point I think at where it lost me... The first in the series (Tunnels) I thought was far superior.

The second book in the Tunnels series. Will, Chester, and Cal continue their search for Will's father. The Styx recruit Cal & Will's mother, Sarah, to help them track down her sons, who they have accused of killing her brother Tam. The boys find friends in their search, but put those friends in danger for helping them. Meanwhile, Will's father continues to search for the answers to the mysteries of this strange new world. Another action-packed installment. Boys, especially, will enjoy this series.

Not that good the second time round took me an age to finish

This book is even better than Tunnels. You get to know more about the characters, and it's surprising how they all react in a very different way to what is happening. I absolutely love Elliot; it was about time to have a strong female character (don't misunderstand, I love Sarah, but she's a whole other story). For some reason, I got too attached to Cal... and I cried like a baby when he died. My opinion of Chester changed so much, that I don't think I like him anymore.
The ending of this book left me in some kind of cliffhanger, and I need like air the next part.
