Pride and Pleasure — Sylvia Day

Wealth has its dangers...

There are disadvantages to being an heiress, as Eliza Martin knows well. Fortune hunters flock to her, acquaintances lie and pander, and lately, someone is engineering "accidents" to propel her to the altar. But Eliza will not be bullied, and she will get to the bottom of this plot. All she needs is a man to infiltrate her assemblage of suitors and find the culprit. Someone not easily noticed; a proficient dancer, quiet, and even-tempered.

...so do certain men

Thief-taker Jasper Bond is entirely too large, too handsome, and too dangerous. Who would believe that an intellectual like Eliza would be seduced by a man of action? But the combination of her stubbornness and the mystery makes the case one Jasper can't resist. Client satisfaction is a point of pride and it's his pleasure to prove he's just the man she needs after all...
