i've not read a ton of mmf, but certainly not one where there's not an established couple taking a third into their relationship. it seems risky to me, since starting a throuple from scratch means you have to do a LOT of trust building between your characters, and i'm not sure that katie nailed it here. a slow start led to a plot that moved at 100 mph, somehow managing to fit in thoughts on PTSD/being a veteran, a multi-day kidnapping moment, a parental come to jesus segment, and an eleventh hour realization that one character is a decade older than the other two and they are "theirs" to take care of. also, this book is mainly them having very satisfying if not sometimes anatomically eyebrow raising sex. i do not know how katie had time for all of their sex and also plot. so, kudos to her there, i suppose.
