This book is a definite keeper! I could not put it down. Endgame House is up for grabs, a “hulking, 17th century gray manor house made from marble and limestone”. Its owner, Liliana, has died, and her will stipulates that her heirs play a Christmas game in order to inherit the house. The heirs include Lily, (her favorite niece/adopted daughter), Liliana’s children, Sara and Gray, and their cousins: Tom, Rachel and Ronnie. The six have from Christmas Day until Twelfth Night to solve 12 riddles; the winner will become the new owner of Endgame. Otherwise it will be left to her cats. But then the bodies start to pile up… If you are a fan of murder mysteries, you HAVE to read this…
