Under Their Skin

Under Their Skin 
by Margaret Peterson Haddix

When Eryn and Nick's mother announces she is getting remarried, they are shocked to learn that their new stepfather has two children, Jackson and Ava, that they were never told about.   To make matters more confusing, their mother and stepfather inform them that they will never meet Jackson and Ava and are ordered not to even ask questions about them.  

With the new marriage comes a new home, one that includes bedrooms for Jackson and Ava.   When Eryn and Nick discover their new stepbrother and stepsister's bedrooms are kept locked, their curiosity grows. Finally, they take a chance one day and decide to do some investigating about the mysterious Jackson and Ava.  What they discover shocks them and changes the way they see the world. 

Under their Skin was a book that, as soon as I started reading, I could not put down!   As with her other books, author Margaret Peterson Haddix's newest book is a thrilling combination of mystery, science fiction, and surprising twists!  Fans of her other books will want to read this first book in her newest series.
