Destroyer's Blood

Blood is mightier than the Sword
Dev is a Master Thief, the son of Prometheus, and a bad-boy with a talking magic sword called Betrayer.
Newly named the Protector of Men by his Titan father, he and Tray prefer to stay far away from Olympus and the squabbles of the Gods. That is until Hermes interrupts them as they climb up Half-Dome with an urgent summons from Zeus.
Before he can finish, his body is torn to shreds by their Enemy...the DESTROYER.
Dev shook his head, spitting out dust and rock chips. The last rays of the setting sun stained the ground crimson. "Betrayer," he murmured, ears still ringing from the terrific explosion, "we have a problem."
The cryptic message from Olympus changes everything...One moment Devcalion and Betrayer are free, climbing up Half Dome without a care in the world, the next they are dragged into battle with the Destroyer, Zeus's ancient foe.
The Dark Power is merciless, and time is running out. It's up to Dev and Tray to try to stop him, or the world of men and gods is doomed.
