Approaching Paradox

At the beginning of an already hectic third year, thirteen year old Hermione Granger is wrenched back in time to 1973 after an accident with her time turner. But if Sirius Black grows up to be a mass murderer, why does Hermione find herself so drawn to him? And why does Peter Pettigrew make her so uneasy? Eventual SBHG. Very slow burn. Currently rated T, will change to M later.
