Duke of Luhst

Lady Chastity Perrin hides her brilliant mind behind plain gowns and scientific journals, pursuing forbidden medical research while society expects her to simply find a husband.

The Duke of Luhst has perfected the art of scandal, his notorious bedroom exploits earning him both his title and a place among London's most sought-after bachelors—despite being his best friend's untouchable sister's childhood tormentor.

When a reckless wager brings them together at a country house party, Lucien's expertise in seduction transforms the bluestocking into a diamond of the first water, while Chastity's unflinching honesty pierces the armor around his wounded heart.

But as three suitors suddenly compete for her hand and a child with unmistakable violet eyes appears, their game of temptation evolves into a fight for everything they never knew they wanted—proving that sometimes the most powerful chemistry happens outside the laboratory.
