As a research scientist, Julia Avers travels through time to sleuth out the mys-teries of past ages. When a rich client commissions her company to send her to 1812 London, she never dreams she’ll land in the townhouse of the Earl of Correlton. He’s handsome, and though she’s from the future, he wants her. Too bad he’s not above stranding her in his home by taking away her only means of escape—her invisibility transmitter. James Noddingdon, the Earl of Correlton, is bored with all the pleasures Lon-don has to offer. When an invisible woman drops into his lap and reveals her-self to him, he feels fate has intervened and given him his intended mate. She claims she needs to find the person who will steal the famed Ring of Claremont. Seeking a way to court her, he demands she stay with him and his grandmother for her week in London. After their week is over, Julia hopes to return home. But will she find that her home—as well as her heart—now rests elsewhere?

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 Marquis 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 Marquis 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.
