Harry get thrown back in time (it was an accident honest) were he meets someone he thought he knew
Responce to the PHGE challange Dumbledore needs to get Harry to Hogwarts safely and comes up with an ingenious way to do so, unfortunally theres some bumps along the way Harry-Tonks
Tonks and Harry start to see each other after the events of OOtP but must keep it secret from everyone. What happens when someone find out? tinker story
My take on how Harry and Tonks could get together and a prequel to Found Out
