Alexia Tarabotti, Lady Maccon, has settled into domestic bliss. Of course, being Alexia, such bliss involves integrating werewolves into London High society, living in a vampire's second best closet, and coping with a precocious toddler who is prone to turning supernatural willy-nilly.

Until, that is, she receives a summons that cannot be ignored. With husband, child, and Tunstells in tow, Alexia boards a steamer to cross the Mediterranean. But Egypt may hold more mysteries than even the indomitable Lady Maccon can handle. What does the vampire Queen of the Alexandria Hive really want from her? Why is the God-Breaker Plague suddenly expanding? And how has Ivy Tunstell suddenly become the most popular actress in all the British Empire?

Timeless is the final book of the Parasol Protectorate series: a comedy of manners set in Victorian London, full of werewolves, vampires, dirigibles, and tea-drinking.
