Clear Sky and Storm. They would've ended up happy, had Clear Sky not been so bossy that she left, had she not died. But she did forgive him, and I believe she still loved him.
That's about it for now. Also, you must get Shattered Sky and Legends of the Clans. Absolutely amazing books! I will give my thoughts about that in a different post. As always, fellow warriors, I will see you later!
