Keiran had such a hard life that i am sure even a grown man wouldn't have survived.  Even with him thinking he was a monster and only meant to destroy and isn't worth loving anyone or anyone love him he sure did find his match with Lake. Even though she kinda got on my nerves with turning him in to still seeing him and couldn't decide what to truly do even though i think deep down she knew he didn't do the killing. That's why she went back and forth her body knew the true him why her head and heart were at war to what was the truth. Did like the twist how everything tied up together especially the last letter he got that one all of it was fate.
