Promise Me [PDF ebook] 

Cathy is in love with Amos, the boy next door. He is everything she could ever want. They talk all the time. He makes her laugh. He even writes songs for her. The trouble is, Cathy has never set eyes on Amos. He locks himself away, and won’t say why. Cathy wants more. She dreams of a normal life with him. But Amos is not a normal teenage boy… Between the Lines is set across a range of locations — in familiar places such as schools and homes as well as spanning the Yorkshire moors, the Mediterranean and South India. Designed expressly for reluctant and struggling readers, the stories in this series feature mature and serious themes touching on abandonment, addiction, loss, homelessness, love, war, dystopia and refugees.
