- "It is at any rate a pleasure to meet such ontologically improbable creatures."
- — Peter Van Houten
He is an alcoholic, and when Hazel and Augustus met him in person, he was abrasive and drunk. He insults them and refuses to answer most of Hazel's questions, effectively crushing her dreams of learning what happens at the end of An Imperial Affliction. He never reads his fan mail, and has tons of it piled up in his household.
Despite being considered something of an authorial genius, Peter Van Houten defies that impression due to his disheveled, rotund appearance; as described by Hazel, "...a potbellied man with thin hair, sagging jowls, and a weak old beard."
Anna Van Houten
Peter Van Houten's daughter, Anna, died at the age of 8 from Leukemia. Van Houten loved her so much she inspired the book An Imperial Affliction. When she passed away, Mr. Van Houten, after writing the novel which effectively gave her a second chance at life as a teenager, became reclusive, bad-tempered, and alcoholic due to being unable to cope with her loss.
- He lives in Amsterdam
- Though he appears to be a heartless drunk, genius intellectual Van Houten lost his way after he lost his young daughter to cancer. He did fly down to Gus's funeral and offered Hazel a sincere apology.
- Like Van Houten, John Green also believes that once the book is finished, the future of the story does no longer lie in the hands of the author, but that of the readers.
