Watts' "Rifters" trilogy is there in its entirety. Also "Blindsight", which is fascinating. His latest book is "Echopraxia", a sequel to Blindsight, which isn't there, but you could always consider buying it if you like his other stuff!
Amusingly, as vampires are/were in fashion, both Stross and Watts have written books featuring nonstandard imaginative interpretations of vampires. Strossian vampires are explainable in the context of Laundry-universe magic, and enjoy investment banking [1], and Scrum practices. Wattsian vampires are resurrected from the dead by human genetic engineering, and have an unfortunate flaw (well, unfortunate for them, fortunate for the humans who enslave them) - "the Crucifix glitch" - that cause them to go into seizures when they see right angles [2][3].
