This review applies for the entire series, the Caster Chronicles. You can also read this review on my blog. 
 In short: Kami Garcia and Margaret Stohl make an excellent team and have written a great series with the Caster Chronicles. 
 I have been doing my best to finish up all the series that I have on the go at the moment because at some point I realized that I had started and never finished a frightful number of series. I will often enjoy the first book in a series and will have every intention of seeing the series through, but then somehow I never get around to it. It's likely that I'll end up dropping a few of the series that just didn't "wow" me with the first book, but in the case of the Caster Chronicles, I knew I wanted to see it through to the end. 
 I absolutely adored Beautiful Creatures when I read it in late 2010, back when I was a newbie blogger. I do think my tastes have changed since then though and if I had read Beautiful Creatures now, as I did with the other three books in the series, I can't imagine I would be quite as enamoured with it as I have since fallen a bit out of love with paranormal YA. But it was with some amount of relief that I found that my tastes haven't changed hugely and I was able to delve back into the little world of Gatlin and the big world of the Casters, no problem. 
 Kami Garcia and Margaret Stohl demonstrate with ease their adeptness in writing great characters and in setting the broody Gothic atmosphere of Gatlin. I am just in awe of their skills, particularly because I can't comprehend how anyone could share the authoring of a single POV book with someone else and still have such smooth passages and transitions that you would never think it wasn't written by one person only. My understanding is that they each write their own passages and then trade and edit each other's work as they go. They must work quite well together! 
 I am happy to report that I enjoyed the rest of the series after Beautiful Creatures, even if I was perhaps not as engaged in the story as I once was. The pacing can be a bit slow at times, but more patient readers will appreciate the attention to detail in the descriptions. The town of Gatlin is as much a character as it is the setting for the series and I absolutely love that about these books. I have also grown quite fond of the characters - particularly the side characters, whom are numerous and yet as richly developed and animated as Ethan and Lena, and whom also provide much needed moments of levity among the dark undertones of the series. 
 So it is with satisfaction that I can officially cross off a series from my lengthy series-to-be-finished list! And I'm all the more satisfied because this series is one that had a good conclusion, as well as an elaborate and well thought out journey on the route there. I may have fallen a bit out of love with the Caster Chronicles since I read Beautiful Creatures so long ago and I may not have been as engaged with the story as I once was, but I am happy that each subsequent book was a solid read and that I enjoyed them. I am so impressed with the work that Kami Garcia and Margaret Stohl do together that I would gladly read more from them again!
