BOOK SUMMARY:

From the author of The Undertaking of Hart and Mercy comes a new heartwarming fantasy rom-com with an opposites-attract twist set in the delightful world of Tanria.

Immortal demigod Rosie Fox has been patrolling Tanria for decades, but lately, the job has been losing its luster. After one hundred and fifty-seven years of being alive, everything is beginning to lose its luster. When Rosie dies (again) by electrocution (again) after poking around inside a portal choked with shadowy thorns only she can see, she feels stuck in the rut that is her unending life.

Thanks to Rosie’s meddling, the portal’s inventor, Dr. Adam Lee, must come in person to repair the damage. When all the portals begin to break down, he declares an emergency evacuation of Tanria. In the mad rush to get out, Rosie and Adam end up trapped inside the Mist. Together.

And uptight Adam Lee in his bespoke menswear seems to know a lot more about what’s happening than he lets on….

Rosie is determined to crack the shell of his cool exterior. But the more she learns about Adam, the more she realizes that they both have personal histories as tangled and thorny as the plant that has them trapped inside the Mist. Maybe two people who have found themselves stuck in this life can find a way to unstick each other … just when their time on this earth seems to be running out.

GOT ME IN THE FEELS.

This series is delightfully quirky with just the right level of heaviness balanced with heart and humor that make me love this writing style. I liked having the time jump before the start of this one and seeing the evolution of Tanria and what some of my favorite characters have been up to.

The set-up for the plot led to a small cast with all the forced proximity you could want (with a bonus side character romance too!!). I really enjoyed the smaller cast. It felt like a very tight knit found family and I fell in love with each one of them.

And I loved the dynamic between Rosie and Adam. His dry wit combined with her more effervescent nature was the perfect blend. Slowly getting Adam’s backstory was fantastically executed and I loved how that mystery unfolded. There were so many memorable moments and key scenes that made you think and ponder life and the price of immortality.

Overall audience notes:

  • Fantasy romance
  • Language: moderate
  • Romance: 3ish open door
  • Violence: moderate
