Came my way: The Last Equation of Isaac Severy: A Novel in Clues
It's a mystery novel about the unexpected death of a Cal Tech mathematics professor, the patriarch of a Pasadena family of troubled geniuses, and the various enigmatic characters trying to get hold of the secret-of-a-lifetime for which he died.
Which all has something to do with Chaos Theory.
The novel fails miserably at the whole "it's a mathematical secret which would change the world" business.
But if you can overlook that (a bit of a challenge, since it's the core of the plot), Jacobs is an entertaining writer and she crafts a number of entertaining characters, and there's plenty of good old family drama, with lots of those Uncomfortable Family Secrets Revealed that writers love to use to add spice to their mystery novels.
Definitely a fine book for making the commute fly by.
