   Summary

   When a ritual misfires, Harry wakes in 1943, right in front of a very young, very baffled Tom Riddle.
   The past is fragile, the future uncertain, and between them lies a bond neither boy can explain.
   As Harry’s feelings for Tom grow complicated, he must decide: return home, or stay and rewrite the past to save the future… and maybe even Tom.
