Hayley Ann Solomon 
An Imperfect Proposal [EPUB ebook] 

With two young nieces now in his charge, the Earl of Devonport is quite suddenly in need of a wife—and kind, gentle Amaryllis Hastings fits the bill nicely. His marriage will be nothing more than a convenience, after all—but his ‚retiring‘ bride surprises him at every turn, especially when he discovers that she has stolen his heart!
