After returning to the BAU following his time in prison, Dr. Spencer Reid is quieter, sharper, and haunted by everything he endured. Then he meets Y/N—a gentle, easily flustered profiler whose warmth seems to be his complete opposite, yet whose brilliant mind and disturbingly accurate ability to think like unsubs rivals his own. As they become the BAU’s strongest profiling duo, Spencer finds himself falling for the one person who can understand the darkness in his mind without ever losing the kindness in hers.
