The title of the new book by Dan Chaon seems so sweet: He called it "Stay Awake," after the lullaby Mary Poppins sings in the Disney movie about the super-cali-fragi-listic-expi-ali-docious nanny. But, in fact, the Cleveland Heights author's book of short stories — just published by Ballantine Books — is anything but restful, Instead, its a compendium of concepts so disquieting that sleep is sure to be elusive.

From the father grappling with his son's night terrors to the trauma experienced by a child sent to live with a foster family, Chaon's haunting suspense is truly a page-turner guaranteed to cause insomnia.

Just be sure to leave the light on.

Chaon will be signing books on February 16 at Joseph-Beth Booksellers in Cincinnati's Rookwood Pavilion and on March 7 at the Coventry Branch of the Cleveland Heights library. Both events start at 7 p.m.
