This novel has everything I like in a good read - a little bit of history, lots of art, fine writing and a great plot. Besides which it's quite long so it lasts a few nights.
The premise is that the artist participates in a scientific study that unexpectedly sends him back to the 17th century or at least puts him into the body or mind of the famous painter Velazquez. He begins to paint like Velazquez. His family life is chaos, and he gets involved with shady dealings. You're never quite sure exactly what's happening in what dimension, but it's a really good uncertainty that keeps you guessing and reading. I highly recommend this for quality escapist entertainment!
