Romy Lupin was a walking cliche. She has her father's metamorphmagus abilities and also seems to be a seer.
During her last year at Hogwarts, Tom Riddle is brought from his teenage years at Hogwarts into the year 2047, and soon after Romy finds herself being sent back into time. Back in 1926 when Merope Gaunt was still pregnant. It's Romy's job to protect Tom Riddle Jr. from being taken into the wrong hands.
It was all going to plan until Merope knocked the time turner and they ended up in 1916, in the middle of the first world war, and with no way to get back to 1926.
There she meets the Shelby's and somehow manages to find her feet in dingy Small Heath with the help of Harry Fenton, Squib, and a distant family member.
