@Shadowhunter164 me, seeing you not want to finish the book:
! SORTA SPOILERS BELOW IF ANYONE WHO WANTS TO READ IT SEES THIS POST !
but LMAO anyways, the book ends off towards the end of 3a, where they're at the hospital with blake and derek and the alpha pack is there and all that jazz. carson doesn't end up with anyone technically where i leave off, BUT the intended endgame for her character if i had gone through the rest of the show would be malia!
