Her Last Flight was generally well received by critics, including a starred review from Publishers Weekly, who wrote, "Williams builds irresistible tension with the alternating timelines as the fate of Irene and Sam unfolds with shrewd twists and turns that build to an unexpected jolt.

"[1] Mike Farris, writing for The New York Journal of Books, wrote that Williams is "a master of the historical fiction genre," proven by this work, among her others.

"[2] Farris concluded by saying, "Williams deftly fits together the characters, stories, and themes that the narrative services into a cohesive whole.

They explained, "Williams' otherwise imaginative novel front-loads a lot of exposition [...] The action is significantly slowed by technical details about surfing and flying that are sometimes engrossing but often gratuitous.

Only halfway through does tension ramp up as Irene and Sam contemplate a future together and confront a giant impediment [...] Plenty of twists ensue, but by now readers may have lost patience.
