Leave the past behind can be really hard, but it can be harder start again. Thunder Luck, a young pegasus sick of the city life, moves with his cousin Caramel, trying to get away from the things that have been tormenting him.
Story 7 of the Savage Skies series. After the tumultuous first few months of Dawn Lightwing's stay in Ponyville, he settles in to spend the autumn and winter with his new family and friends.
Caramel is one of my favourites, sad to see him like this!
Just a heads up - I'll try to get to reading this later today after I finish work :)
