Wagering on the Wallflower — Eva Shepherd

A wallflower

And an elegant gentleman…

Gauche Hazel Springfeld is reconciled to being left on the shelf. At a society ball, she is improbably asked to dance by charismatic Mr. Lucas Darkwood. When she discovers it was all for a wager -- he'll win a prize if he can turn her into marriage material -- Hazel plans to get her own back! She'll frighten Lucas into thinking she really does expect that proposal -- from him!
