Tracy’s Rating: 3.5/4 of 5 stars

Series: Undead Gods #2

Release Date: January 5, 2026

Elysia Parker, the fierce and determined heroine, continues her struggle after striking a dangerous bargain with Aidan, the god of the dead. Her journey is fueled not only by her own survival but by the desperate need to save her sister and her kingdom from the encroaching soot plague. Elysia’s emotional turmoil and stubborn resolve make her relatable and compelling, while Aidan is portrayed with a unique vulnerability—his brooding nature and possessiveness are balanced by guilt and a desperate need for connection.

This installment of the Undead Gods trilogy is fast-paced and brimming with tension. The stakes are enormous, as Elysia races against time to defy the meddling fates and locate the elusive talisman that could save her world. The world building is vivid and atmospheric, immersing readers in a realm where necromancy, underworld chaos, and prophecies collide. Twists and revelations are deftly woven throughout the narrative, maintaining a sense of trepidation as the romance between Elysia and Aidan slow burning, tangled with distrust, longing, and fate that keeps readers invested in their journey. The book’s pacing is a little off at times, but still delivers an intriguing and captivating read. Overall, I enjoyed this story more than the first installment and will be impatiently waiting for the final installment!
