4.5/5 stars
I didn't expect this book to be as LONG as it was, but I think Riordan does such a fantastic job. When I first started the Heroes of Olympus series, I was very weary of the multiple POVs (points of view) but again, Riordan is amazing at creating distinct voices for his characters (which is harder than you might think - you really have to know your characters inside and out to make their voices so distinct from each other).
The House of Hades continues the 7 demigods and no spoilers but I LOVED Percy and Annabeth's POVs. Their journey (again, no spoilers) is a bit different from the other five, and once again, Riordan created such an amazing, vivid scene.
As for the other characters, I've never been crazy about Frank. I feel like we don't really know him that well, but I loved his development here, he's really come into himself and it played out so well. Same with Leo... ugh, I would protect Leo with my life. Little Leo. *sighs*
And Jason and Nico's relationship - talk about an unlikely friendship, but I loved their bonding moments.
I don't know if it was booktube-a-thon or what, but I absolutely flew through this book. I think I may have anyways, but the plot never slowed and that makes it so easy to follow and be excited to keep reading. This is why I recommend Riordan's books so often at the store, I think he's got a talent that makes kids love reading. Basically this review is one giant Riordan shoutout - props to you, man!
