A Robin's wings cannot fly unless trained by his parents. But he's not ready. Not even with the countless little pushes his kin gives. Instead, he does it differently, by sending letters to his beloved. Alexandria Lewis. Their matching tattoos pulse and get scalding hot when near each other, and gives pinches when their significant one is hurt. Little did they know how much it's going to act up when they go out, as Robin and Hummingbird. This is the first book in the Soulmates series. Books don't necessarily have to be read in the order. Obviously I don't own anything DC.
