This is definitely not my type of book. It's about witches (Brujas), but not as much the whimsical, fantastical ones like in Harry Potter, but more about real witches. However, there was an entire fantasy setting in most of it, so it was interesting, and if I was more into the subject, I may have rated it higher, but I'm not, so keep that in mind with my rating.
So, basically Alex (Alejandra) is a Bruja, but doesn't want to be one because she has only encountered sadness when people use it. So when her "death date" comes and she is to be blessed by her family to solidify her powers, she decides to go the other way and denounce everything. A vortex sweeps her entire family (father is missing, so her mom and 2 sisters) into an alternate world where she and her best friend and another boy, Nova, have to try and find them. It kind of reminded me of a Lion, Witch, and Wardrobe story a little bit.
Overall, a well written book, but I will not be going on to the 2nd of the series.
