Hide by Kiersten White

A group of misfits sign up for a contest with a big payout. it is an adult version of hide and seek that will take place in an abandoned amusement park with the last contestant winning a lot of money.
Mack is swimming in guilt after she took her little sister's hiding spot and her dad took her life. The other contestants seem to be equally adrift or have big dreams that the payout can make come true.
Once the game begins the reason they are there begin to come clear and the stakes are much more than just walking away empty handed. They are there to honor a contract made decades before and the game of hiding and being found is death. A little Shirley Jackson's THE LOTTERY or a scary reality show from the mind of M. Night Shyamalan, this is her first adult horror title that will appeal to her young adult fans as well.  4 scary stars
