In March 2011, Baen Books, distributed by Simon & Schuster, released Overkill, Buettner's sixth novel and first in a new series, which will include at least three books. This series is set a generation after the Jason Wander books and includes characters from the earlier series, both directly and by reference. A continuing theme is the search by the protagonist, Jazen Parker, for his parents.

Buettner's first novel, Orphanage, made numerous bestseller lists, including Barnes & Noble's overall paperback Top 50 and the Locus Magazine paperback Top 10. Orphanage was nominated for the Quill Award as best Science Fiction/Fantasy/Horror novel of 2004. Orphanage's publisher (which changed its name from Time Warner Aspect to Little Brown Orbit) reissued Orphanage in April, 2008. As of June, 2008, the book was in its sixth printing. Orphanage, as well as others of Buettner's novels, has been translated by foreign publishers into Chinese, Czech, French, Japanese, Russian and Spanish, was published in hardcover by the Science Fiction Bookclub, and as an ebook in various formats. Orbit also markets the Jason Wander series in a separate edition geared for the United Kingdom market. The rest of the series is believed to have performed similarly to Orphanage. Buettner's subsequent series, the Orphan's Legacy series, was a nationally bestselling series. Particularly, the third book, "Balance Point" was a Bookscan national bestseller when released in trade paperback in April 2014.

Tor.com Other critics have compared Buettner's books favorably to the work of "Golden Age" science fiction writers Poul Anderson, Andre Norton, H. Beam Piper, L. Sprague de Camp, to recent writers Joe Haldeman and John Scalzi, and to such diverse artists as Miguel de Cervantes, Monty Python and P. G. Wodehouse. Buettner was nominated for the Quill Award for Best New Writer in 2005. Orphanage was nominated for the Quill Award as best science fiction/fantasy/horror novel of 2004, and has recently been described as "one of the great works of modern military science fiction." Buettner's novel Balance Point was also reviewed favorably. Publishers Weekly said his 2017 novel, "The Golden Gate" was a lavishly detailed narrative...[that] reverberates with current concerns over life extension [and its ] underlying mystery and unpredictability keep the pages turning." The science fiction review Tangent called it an "entertaining, thought-provoking read smartly-told...with just the right touches of SF, history, and science."
