The Thornthwaite Inheritance by Gareth P. Jones

The Thornthwaite Inheritance is a book that I really enjoyed.
The main characters are orphaned twins, Ovid and Lorelli Thornthwaite. For as long as the children can remember, they have been trying to kill each other. On their thirteenth birthday, Lorelli and Ovid decide to make a truce, inviting a lawyer to come and stay with them in thornthwaite manor, where they live under the care of their butler, their cook, their nurse and their gardener. But even as the lawyer is amending their parents will to confirm their truce, more attempts on the twins lives are being made.
This book was really well executed because I loved how seemingly unimportant details at the beginning played a role in solving the mystery. I also liked how the other characters plots tied in with the twins' plot in surprising ways.
Although the themes in this book seem quite dark, (death, greed, betrayal, murder,) it does not go into any gory details, and is told in a style that makes you relate to the characters, it is emotional without being to gushing or sentimemtal, and at times it is funny.
I would reccomend this book to my friends aged about 9 and up.
This book is outstanding in the style and ideas of the book.
