Lars Kepler

Lars Kepler is the pseudonym of critically acclaimed husband and wife team Alexandra Coelho Ahndoril (b. 1966) and Alexander Ahndoril (b. 1967), authors of the No. 1 internationally bestselling Joona Linna series. With nine installments to date, the series has sold 17 million copies in 40 languages. The Ahndorils were both established writers before they adopted the pen name Lars Kepler, and have each published several acclaimed novels.

“I’m a fan for life!”
Tami Hoag, #1 New York Times best-selling author of The Boy

“Kepler treats us readers to a nonstop roller coaster of suspense, taking us deep into the hearts and minds of perfectly realized characters.”
Jeffery Deaver, #1 New York Times best-selling author of The Goodbye Man

“Kepler’s characters, particularly Joona Linna, are always drawn sharp and deep, like scalpel cuts. Kepler’s prose unrolls as smoothly as a loop of razor wire. But it’s Kepler’s storytelling that really draws blood.”
A. J. Finn, #1 New York Times best-selling author of The Woman in the Window
