Thicker Than Water — Natasha Deen

Zack Bernard has a thing for crime shows, especially the forensic-investigation kind. So when his friend Ella goes missing, Zack can't help piecing together what he thinks is concrete evidence that could lead to her whereabouts. The problem is, it's all pointing toward his dad. He knows his dad is lying about not having seen Ella because Zack saw them together at the mall the day she disappeared. What he doesn't know is why. With the help of his friend Ayo, Zack tries to solve the mystery himself to avoid having to make the terrible choice between losing someone close to him and betraying his family.
