First off, I'm going to speak about the whole series here because I read the books back to back and might not do a great job of separating them. I got The Palace Job for free on a special promotion, and I bought and read the next two as soon as I got the chance. Totally worth it. The series was so much fun that I have to recommend it even if there is crass, off-color humor throughout.
Imagine if 'Oceans 11' got a lot more diverse and was transported to a well-plotted fantasy universe. Like you might expect, the story is more about plot and humor than driven by character, but still the characters were anything but flat. Each acted according to his or her predisposition, and despite the number of them they never blended together. This is a fun, fast paced, outrageous story, kind of like the A Team with a magic system. I regularly struggled not to keep my husband up, chuckling as I stayed awake reading past my usual bed time.
Language/Sexual Content: I merged these categories because pretty much the only foul language was sexual humor, and just about the only sexual content is innuendo and coarse jesting. For example, there's a unicorn whose goal in life is to seduce virgins, but nothing is ever actually described. One character consistently distracts his opponents by claiming to have been spending 'quality time' with their mothers. Another is a love priestess and spends her days trying to help people find romance. If you're sensitive to that sort of thing, this isn't the book for you because there's a lot of it. Personally, I admit that some of it was funny and the rest of it was easy to gloss over. The only exception is in one part of one book where an evil Satyr came into the story and for a short bit the story got a dark, illicit feel to it, but fortunately that didn't last for long.
Violence: Lots of hand to hand combat. I'm trying to remember any really gruesome, explicit content, but I can't.
Overall Message/Plot: I'm going to say this is an overwhelmingly plot-centered story, and well done. It's wonderfully diverse, keeps you on your toes, and still manages to keep consistent, endearing characters. I'll reread it at some point.
Also, an aside worth mentioning: The author is a white guy. I only mention that because the main characters are shades of brown and when I read the book I assumed the author was a person of color. Why? Because I don't often find characters of color filling the leading roles in books not written by people of color, and if I do, it seems the authors are women like me who have somewhere along the way developed a vested interest in diverse stories. (Yes, I know there are exceptions, but they're exceptional enough to make note of.) I wish I had a good way of reaching Mr. Weekes because I would absolutely love to know what inspired him to write diverse characters, and to tell him how much it means to me that the pool of non-white heroes is growing. It's important for my son to grow up seeing his own skin reflected on powerful (if flawed) world-savers.
