What’s it about?
The Blood of Olympus is the last one of the Heroes of Olympus series by Rick Riordan, he of the Percy Jackson fame. It was a pretty standard Rick Riordan book – mythical creatures, snarky teenagers, two heroes that it’s maybe kind of hard to tell the difference between. There are battles, one of which happens in Greece, the other of which happens at Camp Half-Blood. The prophecy was fulfilled. Nothing was surprising – it was comforting that way.
Why should you read it?
You should read it if you’ve read the first four books. If you’ve made it this far, why not finish up the series?
