The Inheritance Games by Jennifer Lynn Barnes

Ever find that book that you can't put down? That book that makes you stay up far later than you should, knowing you are going to miserably tired in the morning, but you stay up to read it anyway, because you just need to know what is going to happen? Well The Inheritance Games is that book!
When a complete unknown is given their grandfather's entire inheritance - an inheritance worth billions, the Grayson family is completely blindsided. Avery Grambs is also blindsided - why was she named the heir and why does she have to live in his house with his entire family for a year before the fortune becomes hers? Danger, suspense, puzzles and twists galore will keep readers running to the books conclusion. While this is the first book in a new series, it does come to a conclusion at the end, while still leaving room for a sequel. Highly recommended for grades 7 and up.
