Riley Sager

Todd Ritter, also known under the nom de plume of Riley Sager and Alan Finn, is an American author of thriller novels.

Biography
Ritter grew up in a ranch-style house in Pennsylvania. Before becoming a full-time novelist Ritter worked as a journalist, editor and graphic designer.

Writing career
As of 2022 Ritter has released six novels as Sager and three novels under his real name, the latter of which make up the Kat Campbell series. Ritter has also released one novel under the pen name Alan Finn, Things Half in Shadow. He referenced the choice to write under the name Sager, stating that "since we were looking for a new publisher, one could argue that editors would be willing to go with someone who had a clean slate, rather than a critically acclaimed author with a spotty sales record." The author's website for "Riley Sager" initially lacked an author photo or any gender identifying language, including pronouns. This has since changed, as the current website features a photo of Ritter and uses he/him pronouns.
