E.L. Konigsburg is the author of From the Mixed Up Files of Mrs. Basil E. Frankenweiler (I think that's the title; I'm not bothering to look up the spelling), which I love. I've read a couple of her other books and really like her voice/writing style. I was excited about this one because it's her take on why a thieving apprentice might have been important to Leonardo da Vinci and why LdV might have painted an unknown merchant's second wife when he had all the big names in Italy begging him for a portrait.
Clearly she loves the Italian Renaissance era and finds it fascinating, as this is the second (as far as I know) of her books that deals with a secret behind a beautiful artwork by a
Salai as the protagonist is almost entirely unlikeable. He has no moral scruples whatsoever and is completely baldfaced about it, with no negative repercussions to anything he does. The tone of the book didn't match with Salai's tone and vocabulary, which was weirdly slangy in a 20th century way. Despite the title, the subject of the Mona Lisa literally enters the book about three pages from the end. According to this book, Leonardo painted the portrait of this second wife of a nobody merchant because Salai saw that she was basically who the duchess would have been had she lived, and he talked Leonardo into doing it. Yep. Freaking Salai. I don't hate this book, but I feel annoyed that ELK didn't turn it into what it could have been. This could have been really something. It's like you had all the necessary ingredients to make a really good cake, but instead you have a weird flat boring doughy substance that is edible and not that bad but it makes you mad because you could've had delicious cake! 3/5 stars probably
