Constant as the Sun — Diana J. Oaks

Elizabeth Bennet's father imposed a six-month delay to her taking the name of Darcy, requiring a London season in the interim. Unknown to her, a secondary clause could spoil it all: If she is unhappy among the elite, he will rescind his consent to the marriage. Faced with the expectations of Darcy's relations and the standards of the ton, Elizabeth is immersed in a whirlwind of change, intrigue, and betrayal that not only threatens to ruin her hopes, but puts the lives of those she loves at risk. Constant as the Sun is the second book in the One Thread Pulled series.
