The Silver Linings Playbook by Matthew Quick

Meet Pat. Pat has a theory: his life is a movie produced by God. And his God-given mission is to become physically fit and emotionally literate, whereupon God will ensure a happy ending for him — the return of his estranged wife, Nikki. (It might not come as a surprise to learn that Pat has spent time in a mental health facility.) The problem is, Pat's now home, and everything feels off. No one will talk to him about Nikki; his beloved Philadelphia Eagles keep losing; he's being pursued by the deeply odd Tiffany; his new therapist seems to recommend adultery as a form of therapy. Plus, he's being hunted by Kenny G! In this enchanting novel, Matthew Quick takes us inside Pat's mind, showing us the world from his distorted yet endearing perspective.
