My son has really enjoyed the Hunger Games Trilogy but doesn't want to read the other series I bought for him, Inkspell etc. I have no idea what else he would like, he has rejected our old John Wyndham and Stephen King books. I see Suzanne Collins also has the Underland Chronicles but these look as if they might be for younger children? He also likes all the Alex Rider books. Can anyone please recommend something he might like. Thanks
