A big thanks to Kensington Books for an ARC. Little Sister is a fast paced psychological thriller, that got me turning pages within seconds. The story is about two sisters Emily and Jess, who were very close while growing up. Hardly an year apart in age, they made sure to look after and complement each other. But as years passed, their relationship somehow fell part, and are now estranged. Less do we know, that the reasons for them moving apart, is far more dangerous than just a sisters fight!
