This book was everything I didn’t know I needed! It was such a gift to get an insight into Aria and Tobias again—raw, intense, and so beautifully written. I was a little hesitant at first, worried it might lean too heavily into spice without much plot, but halfway through, it completely surprised me. The emotional depth, the heartbreak, the way their story unfolded—it was gripping.Leigh Rivers once again delivers a masterpiece, perfectly balancing passion with powerful storytelling. If you're a fan of the Edge of Darkness universe, this one is an absolute must-read.
