Heir of Nothing: Bowen's Saga: Mercy Temple Chronicles, Book 9 (Unabridged‪)‬

A banished vampire prince walks into a neon-soaked dive with a tumbler of blood-spiked whiskey and one goal: burn the Duskrender assassin guild to the ground. Bowen (Vorigan bloodline, formerly very royal, currently very done) is hunting two traitors tied to a mysterious shipment and a deadly alliance with the reapers—a trail that drags him from Nashville’s Underground to Sector 16 on Lake Erie, where sirens smile and secrets bite. 

He’s the exiled heir with a past the Royal Council would rather stay buried, a grudge with “Prince” Radomir, and a heart that still bleeds for his demon love. This time, he’s not asking permission. Expect urban-fantasy vengeance, assassin-guild intrigue, shadow-market deals, and a reaper-run fight ring where the house always rigs the odds. Allies? Maybe. Rules? Optional. Bodies? Regrettably plentiful.
