Referred to as his "most didactic novel", ''The Cider House Rules'' (1985) is the sixth novel by ''Creator/{{John Irving}}''. It centers around the story of [[HeartwarmingOrphan Homer Wells]], an orphan in the Maine town of St. Cloud's, and his caretakers: the resident doctor and head of the boy's division, [[FunctionalAddict Dr. Wilbur Larch]], and his two aides, [[TeamMom Nurse Angela]] and [[UnrequitedLoveLastsForever Nurse Edna]]. Dr. Larch raises Homer and trains him in obstetrics, but Homer is reluctant due to his mentor's performance of illegal abortions at the hospital, which Homer is morally opposed to. The novel highlights the importance of personal convictions and purpose and weighs the two sides of the abortion debate.

The book was made into a movie in 1999, starring Michael Caine and Tobey Maguire.

----
!! The book and film provide examples of:

* AdaptationDistillation - The film leaves out quite a bit of the story, and takes place over a much shorter time period.
* AdaptedOut : Many characters due to the AdaptationDistillation, but primarily Melony, Angel, and Nurse Caroline.
* ArtisticLicenseMedicine: [[DeconstructedTrope Deconstructed.]] Most of the period medical information is taken from the notebook of John Irving's grandfather, a doctor from the same time period the story is set. The book compares Dr. Larch's medical and ethical practices to the quackery of the day while simultaneously examining how much these techniques have and have not changed.
