Hello everyone, I seriously need help in finding a book series I read about 5-6 years ago I believe. The genre was Young Adult I believe. The plot details I remember are that the protagonist who was a boy was claustrophobic because a tunnel collapsed on him in his backyard when him and his brother were digging back there. This is found out in the third book I believe. In the first book the boys brother goes missing I think so he goes to try and find him and ends up going underground, at one point he meets a girl who knows his brother and she decides to help him. They cross a river named Styx. Her and the boy have to run from some dogs of people and in order to do so go through a very small tunnel which the boy doesn’t want to do because of his claustrophobia. Other random details I know are, there are elements of terrorism involved and one character says that modern day investigators and FBI are too reliant on modern technology, whereas older generations Willy’s have probably caught the bad guys by now. Thank you for your time.

It’s not the book series tunnels. I know that. I have read tunnels and it’s not tunnels, I promise.

Thank you for commenting though and trying to help me.

The book series is called Beneath by Roland Smith.
