This book was okay. I didn't feel invested until the last quarter. I enjoyed the dynamic between Hades, Zeus, and Poseidon—very amusing, especially the portrayal of Zeus—and the respective vibes of both Artemis and Hades, the latter of whom is more bumbling and misunderstood than anything else. Things get dark near the end, so pay attention to the trigger warnings provided at the beginning of the book. I originally read a library copy, but I liked it well enough that I bought my own copy and I'm looking forward to the next volume.
