The Incredibly Dead Pets of Rex Dexter — Aaron Reynolds

Rex Dexter is itching to have a dog. He was practically born to have one. His name is Rex, for crying out loud. It's a dog's name. Any pooch is preferable, but a chocolate Labrador is the pinnacle. The best of the best. The dream of all dreams.

When Rex's B-Day for Me-Day finally arrives, his parents surprise him with a box. A box with holes. A box with holes and adorable scratchy noises coming from inside. Could it be? Yes! It has to be! A . . . a . . .

Chicken?
Pet poultry?
How clucky.

One hour and fourteen minutes later, the chicken is dead (by a steamroller), Rex is cursed (by the Grim Reaper), and wild animals are haunting Rex's room (hounding him for answers). Even his best friend Darvish is not going to believe this, and that kid believes everything.

Rex's uninvited ghostly guests are a chatty, messy bunch. And they need Rex to solve their mysterious deadly departures from the Middling Falls Zoo before it happens again.

But how?
