So this was the last of Barnes’s books and now I will have to wait forever for another :( But this was totally cool because I love reading about all things Sidhe (i.e. faery) related. It starts out a la sisterhood of the traveling pants, but then takes a fantastic turn. Four very different, but very close best friends are at the mall and one gets these cool looking temporary tattoos. So they all decide to put one on. Turns out the tattoos give them supernatural powers and that a great evil is coming to destroy humanity. But what can four teenage girls do? Quite a lot it turns out. In a completely surprising twist at the end, they find themselves battling evil and one will shoulder a responsibility that no mortal has ever born. It was great at intertwining different stories and leaving you surprised til the very end. I wonder if there will be a sequel? I didn’t see anything about one on her website, but you never know. But at least now I have a new great author I can add to my list. If only they would write faster!!!!
