Speaking of summer : a novel
(Book)

"On a cold December evening, Autumn Spencer's twin sister Summer walks to the roof of their shared Harlem brownstone and is never seen again, the door to the roof is locked, and no footsteps are found. Faced with authorities indifferent to another missingwoman, Autumn must pursue answers on her own, all while grieving her mother's recent death. With her friends and neighbors, Autumn pretends to hold up through the crisis. She falls into an affair with Summer's boyfriend to cope with the disappearance ofa woman they both loved. But the loss becomes too great, the mystery too inexplicable, and Autumn starts to unravel, all the while becoming obsessed with murdered women and the men who kill them."--,Provided by publisher.
