PI Tres Navarre is planning on a quiet summer of academic teaching in Austin, but his peace is broken by the murder of his brother Garrett's business partner, a tech start-up whizz kid whose death leaves Garrett as the leading suspect.

Something - or rather, someone - sinister is at work, as evil stalks the streets of Austin and leads Tres to hunt for secrets lurking at the bottom of a beautiful lake. But the killer won't go down without a fight.

Oozing with Texan mystery, The Devil Went Down to Austin is the fourth book in the multiple-award-winning suspense series by the internationally bestselling author of the Percy Jackson novels.
