Crookedstar's life started off crappy. First he fell off the Stepping Stones and broke his jaw causing his mother to disown him due to his deformity. Then, Mapelshade showed up and it seemed like everything was going to be fine. She made him make a promise he thought he could keep and when he did she trained him like an apprentice. Then bad things started to happen anytime he got emotionally close to anyone they died. First his mother ,then Shellheart ,Willowshine, two of his newborn kits, Oakheart, and finally Silverstream. quote from the book: "No Mapelshade you haven't won because no matter who you take from me I will always have my clan".
