It's been a while since the last time i didn't want to give 4-5 stars to an Olympus series book. But this time frustrated me. The heroes are still loveable, the writing is still enjoyable and funny and dark when necessary. It's just... If you're going to fight 10 super-powerful monsters, and you use the exact same strategy to avoid fighting them, and it works 10 times, readers will get bored.
