As expected, Landwin Brood doesn’t appreciate Theo’s new bond to Ren Monroe; despite her brilliance and magical prowess, Landwin won’t look past her Lower Quarter origins. Although Landwin attempts to separate them, Ren maintains her single-minded focus on revenge. Unbeknownst to Thugar, the eldest Brood, Dahvid and Nevelyn Tin’Vori, who are in hiding, are also out for vengeance as descendants of another family who fell victim to the Broods. Their alliance with Ren and Theo (if he can be trusted) will be the key to bringing down House Brood, but success hangs delicately on an intricate plan that could go wrong in deadly ways. While this sequel to A Door in the Dark (2023) has less breakneck action and high-octane adventure than the first volume, it more than compensates with a slow-building and intensely suspenseful plot that plays to Reintgen’s strength in creating well-defined, emotionally convincing characters. The novel is narrated in multiple third-person points of view, and Ren and Theo’s romance keeps pace, developing slowly but skillfully into something undeniable and sparkling. Themes of loyalty, familial expectations, and personal choice are woven into a world that makes space for sharp-edged girls, tender-hearted boys, and everyone in between. Central cast members are cued white.
