The Missing Grooms — Cindy Holbrook

FIRST THERE WERE SEVEN...
Lovely Lady Julia Wexton must wed in six months -- or control of her fortune goes to her father's ward, incorrigible ladies' man, Garth Tolton. With her dotty Aunt Clare's help, Julia creates a master list of every acceptable suitor in the ton, and finds that each is willing to propose. Her problems seem over...until one by one her suitors vanish!

...NOW THERE IS ONE
Garth Tolton, Earl of Sanderson, had forgotten how pretty Julia is. And now she is in terrible trouble -- and so is he! The ton is calling Julia a curse, and she's calling Garth the cad behind the outrage. So he's making a proposal, too...that they join forces to solve the mystery of the missing men, not knowing that it may lead them into danger, or perhaps into the deeper mystery called love....
