Indiana Jones meets Bridgerton in this delightful romance from a New York Times and USA Today bestselling author.

'A champagne fizz of a romance.' —The New York Times

Bold, curvy Elizabeth Wynchester loves cuddling hedgehogs almost as much as she adores vanquishing villains with the sharp blade concealed inside her cane. Despite others' opinions about her body and gender, nothing will stop her from seeing justice done. 

When her next mission drops her at the dastardly Earl of Densmore's castle, she's prepared to duel like gentlemen—only to be locked inside! Her trusty sword cannot defeat the castle's hidden traps . . . or protect her heart from the devilishly handsome rogue guarding the keep.  

When reclusive inventor Stephen Lenox agreed to impersonate his cousin for a few days, he didn't expect the earl to vanish altogether. Nor could Stephen predict mounting death threats . . . or the arrival of a beguiling, blade-wielding spinster who declares herself his new bodyguard.  

As the earl's enemies lay siege to the castle, Stephen fights his way past Elizabeth's defenses. She'll share his bed, but when the adventure concludes, she vows to sever their affair. Unless he can somehow convince a swashbuckling siren to surrender her heart . . .
