Adam Rex investigates in this hilariously heart-warming tale based on one of the best-loved Christmas carols.

Our hero is having a lonesome Christmas away from his true love. So when she sends him a gift, of course he loves it--even if a partridge in a pear tree wasn't exactly on his wishlist.

Twelve days later, his home is crowded with more birds, milkmaids, pipers, and other guests than he can possibly make sense of. Why would his true love think he'd like this?!

His search for answers transforms the disaster into a source of joy for the whole town--complete with a parade, a circus, and a fundraiser for the school library. By the time his true love gets home, the man finally understands what she's given him: the true meaning of Christmas.

But she has no idea what he's talking about-- the whole thing was a wacky online shopping mixup. All she'd meant to buy was a pair of gold engagement rings. She meant to propose!

Adam Rex, creator of School's First Day of School and many other beloved books for children, strikes again with this hilarious twist on a classic carol. Sardonic and earnest in equal measures, The Thirteenth Day of Christmas is a hit for any day of the year.
