Saving Lord Avingdale

Maryanne loves being invisible, and her job as a time-traveling research scientist fulfills that desire. But when her invisibility transmitter malfunctions, the worse possible person—the Marquess of Avingdale—finds her. Handsome and debonair, the marquis shows interest, but his death is the reason she traveled back to 1813 England. When he forgoes a tryst with a married woman that would've proved deadly, Maryanne fears she's changed the handsome lord's future by ensuring his survival. 

Jonathan Blakely, the Marquess of Avingdale, is on his way for an assignation with his latest lover when he spies the intriguing, yet socially awkward Maryanne at a house party. She's crass in the most endearing way, but she's keeping secrets—ones he is determined to find out. The more she avoids him, the more he's compelled to solve the enigma she presents. What he doesn't wager is that doing so will transport him to a new world of wondrous inventions and tie him to Maryanne in a way he never thought possible.
