After nine years, the universe which demigods inhabit have closed off an arc with the Blood of Olympus. The conclusion to the Heroes of Olympus was delivered with the tag #therewillbeblood and as promised, blood arrived.
No spoilers for the book, but there was blood and tragedy in the finale of the series. It's only pitiable that Riordan didn't deliver everywhere else. The book was definitely solid. Heart pounding action, enjoyable character banter, and a heartwarming final chapter help the Blood of Olympus send of the series with flare. So where does it underwhelm?
