Fourteen-year-old Haley is struggling to cope. She?s got a new stepmom and baby brother. Her cousin Jake is dying from a terminal illness. Her grades are slipping. And the boy she likes is dating her best friend. But all that?s nothing compared to what she uncovers when she digs deep into her family history for a school project. Now she?s got a blood-stained glove, eerie messages on the TV screen, and ghostly images on her camera. Just what?or who?has Haley unearthed? Haley must overcome her own doubts and confront a vampire in order to save herself and her family. Inspired by a true New England story, Mercy is accomplished children's author Sarah L. Thomson's first book for Islandport Press.
