Book 3: Where The Dandelions Fly. This is definitely a very deep and emotional book. Kade has to sacrifice his own happiness to keep Mena safe from him, but wouldn't you want the choice to choose for yourself whether you would risk it or not to be with the one you love?
Then there's Vance, absolutely perfect for Mena, but she has no feelings for him. Ugh, why can't our heart and mind ever agree?!
