Forge of the Gods 3
Cameron's third year as the only male demigod of his generation starts with everything going right, only to be touched by tragedy. His mentor is dead, and everyone thinks she took her own life... but Cameron knows better. And he won't stop until he clears Sarah's name and, heck, maybe do a bit more than that.

When you're a Greek demigod, you can do more about death than whine about it. You can go right down into the underworld and take the matter right to Hades. But the god of death won't just give up the goods without something in return.

Good thing, with the help of his beautiful demigoddesses, Cameron has the talent to make it happen, assuming he can survive the special training to forge what Hades wants, win over a hot dawn goddess, and beat an army of monsters in the process.
