When Sophie Reed empties her every resource into a spirit summoning ritual, the universe sends her Leo Hayes, a cheerful young man in catastrophically loud floral shorts. The crowd loses it.

In the middle of the night, my husband started talking in his sleep. "My little treasure, Daddy's taking you and Mommy to the new house tomorrow." But we were using protection.
