This is the last Anna Hibiscus book which makes me very sad. I wish this series would go on forever.
I was nervous when the first story was a light one about Double and Trouble. It felt a little out of place with the series, like maybe it was meant for an earlier book or should have been a picture book instead of a chapter in Anna Hibiscus. But the rest of the book is so good it made up for the first chapter. Seriously, so so good. And I cried so so much. In a good way.
I thought the climax of the book would be... more climactic. I'm really struggling to remember anything about this book. Events from the last three keep getting mixed up in my head. That's not a great thing.
Overall, the new characters were my favorite part of the series. I really admire Riordan's commitment to writing diverse characters and response to fan criticisms of his work.
Again, I lost my notes on The House of Hades. I vaguely remember comparing it to the Harry Potter series as I was reading this one.* While the book feels dangerous, I don't know that I ever believed any of the characters would die.
I like that we hear the story from several characters, but sometimes that does make for confusing reading. Especially since the characters aren't all together anymore.
*The comparison was unfavorable towards The Heroes of Olympus, but then the comparison was unfair to begin with. Very few series should be compared to Harry Potter.
If I took any notes on the last three books of the Heroes of Olympus, I lost them along the way. This is probably an inflated review. I kept thinking, I'll know how I really feel about The Mark of Athena after I finish the series which probably means it was a typical middle book. It set up some stuff, but in the long run left me with loose ends more than anything.
