A bestselling legal and adventure thriller by John Grisham. The story begins when billionaire Troy Phelan unexpectedly commits suicide after leaving a shocking final will that disinherits his heirs and leaves his vast fortune to an unknown illegitimate daughter living deep in the Brazilian rainforest.

Lawyer Nate O'Riley is sent to locate the mysterious beneficiary, Rachel Lane, a missionary working among remote indigenous tribes. His journey takes him far from the courtroom into the heart of the Amazon, where he confronts personal struggles, moral questions, and a battle over one of the largest inheritances in history.

Combining legal drama, suspense, adventure, and themes of faith and redemption, The Testament is one of Grisham's most distinctive and thought-provoking novels.
