It's In His Kiss, by Julia Quinn, is currently marked down to $1.59, the same price as The Epilogue II (which expands the characters lives after the end of the main book, something she has done for a number of other novels she has written; generally these are quite short, not even novella length, unlike the main novel, which is 384 pages in paperback).
Book Description
Meet Our Hero ...
Gareth St. Clair is in a bind. His father, who detests him, is determined to beggar the St. Clair estates and ruin his inheritance. Gareth's sole bequest is an old family diary, which may or may not contain the secrets of his past .. and the key to his future. The problem is -- it's written in Italian, of which Gareth speaks not a word.
Meet Our Heroine ...
All the ton agreed: there was no one quite like Hyacinth Bridgerton. She's fiendishly smart, devilishly outspoken, and according to Gareth, probably best in small doses. But there's something about her -- something charming and vexing -- that grabs him and won't quite let go ...
Meet Poor Mr. Mozart ...
Or don't. But rest assured, he's spinning in his grave when Gareth and Hyacinth cross paths at the annual -- and annually discordant -- Smythe-Smith musicale. To Hyacinth, Gareth's every word seems a dare, and she offers to translate his diary, even though her Italian is slightly less than perfect. But as they delve into the mysterious text, they discover that the answers they seek lie not in the diary, but in each other ... and that there is nothing as simple -- or as complicated -- as a single, perfect kiss.
