This series has proved the exception to two of my general practices 1) I don't binge series, and 2) I don't read series that are more than 3 books long.
This is the 4th and penultimate book in the Tear Down Heaven series, which I've torn through over the past few months. I'm usually fine to read a few other books before I pick up the next in a series, but not so with this one. I finished book 3 in August and then had to beg Rachel Aaron to send me an ARC so I didn't have to wait until October; fortunately, she was kind enough to oblige me. The only problem is that I now, again, have to wait for the next book, but you, dear reader, are in a luckier position that me. Because if you start reading this series now, even if you tear through it, by the time you're caught up, book 5 should just about be ready to be released.
As mentioned, this is the 4th book in the series, and while each book is a satisfying, self-contained story arc, they don't really stand alone. What's more, the overall series is building in a satisfying series-long arc, which is something that a lot of series fail at. I have to imagine book 4 is one of the trickier ones to write; you're kind of in the second half of Act 2, you've got to balance of its events being important but not definitive for the overall, but Aaron manages that balance.
Like the other books, this one culminates in a huge, epic battle, but the entire book is the battle, while the other books had other other plot lines going. As such, there's less time for character development, which is okay because the characters have been developing over three books, but I did sometimes wish for a little more downtime in the action.
Overall, though, if you like action, epic battles, and expert world building that is detailed but never seems to drag, you'll enjoy this series. The books are fun and fast but also smart and heartfelt. These are perfect if you want the pleasure of a book that is completely escapist but that still has substance.
And even though I got an ARC ebook for free, but I'll be buying the physical copy to as soon as it's released to add to my shelf alongside the first three books. I am eagerly awaiting book 5.
