The Dark Days Deceit, by Allison Goodman
Lady Helen has retreated to a country estate outside Bath to prepare for her wedding to the Duke of Selburn, yet she knows she has unfinished business to complete.
She and the dangerously charismatic Lord Carlston have learned they are a dyad, bonded in blood, and only they are strong enough to defeat the Grand Deceiver, who threatens to throw mankind into chaos. But the heinous death-soaked Ligatus Helen has absorbed is tearing a rift in her mind. Its power, if unleashed, will annihilate both Helen and Carlston unless they can find a way to harness its ghastly force and defeat their enemy.
“Charged with excitement, danger, more than one romance, secrets, and deceit, the plot moves inexorably to the final showdown...[and] to an extremely satisfying ending... a conclusion that continues the strong writing, well-developed characters and rich details of the Regency period of this series. VERDICT An excellent blend of historical romance, adventure, fantasy, and ghost story." -School Library Journal
"'Goodman's assured writing and masterful grasp of historical milieu create a world where doing one's hair can take hours--and is done even when the end of the world is at stake. The slow burn, punctuated by murder, forbidden declarations of love, and surprising plot twists provides readers... with exactly what they want...You'll never see the Regency the same way again. -Kirkus
