''Griffin and Sabine: An Extraordinary Correspondence'' is a trilogy of {{epistolary novel}}s written by Nick Bantock. The story begins when Griffin Moss, an artist living in London, receives a postcard from a woman he's never met. The woman is Sabine Strohem, a citizen of the Sicmon Islands, who somehow knows things about Griffin's art that no one but Griffin himself could know. Sabine soon reveals that for the last 13 years, she has been able to "see" his drawings and paintings as he is creating them. The two soon become pen pals and begin a long distance relationship, while mysterious forces keep them apart and a strange man investigates their PsychicLink.

!! Tropes that appear in the books:
* AlternateUniverse: Sabine and Griffin appear to be living in two of these.
* EpistolaryNovel
* ForScience: The reason Frolatti wants to study their telepathic connection. In his second postcard to Griffin, he claims the two of them have a "moral and social obligation to allow the scientific community access to your experiences."
* HappilyAdopted: In her letters, Sabine says she was abandoned as a baby and adopted by an Island couple. She seems to have been pretty happy with them. Griffin was also adopted by Vereker after his parents died.
* ImaginaryFriend: At the end of the first book, [[spoiler: Griffin tells Sabine that this is all that she is, his ideal woman that he made up to assuage his loneliness. And she [[NotSoImaginaryFriend writes back, coldly informing him that he has another thing coming.]] ]]
* IJustWantToHaveFriends: Griffin.
* LoveBeforeFirstSight: Griffin and Sabine fall in love through their letters, without ever meeting each other.
* LoveTranscendsSpacetime: Maybe. The two appear to be living in alternate universes. When Griffin tries to visit Sabine in the Islands, he never makes it there and nearly drowns. It's implied that the Sicmon Islands don't even exist in Griffin's universe; in his letter to Sabine after the incident he tells her he wasn't sure if the captain of the boat even knew where he wanted him to take him. The second time they try to meet, they end up staying in the same house for a week without ever coming across each other.
* Paparazzi: Victor Frolatti claims that he's a medical journalist, but Griffin and Sabine suspect that he works for a tabloid newspaper.
* ParentalNeglect: Griffin claims his parents fought all the time and ignored him, so much so that their death in an accident "barely touched him." He saw them more as cartoon characters than actual people.
* SanitySlippage: This may be happening to Griffin throughout the trilogy.
* SequelHook: The last postcard in ''The Golden Mean'' (see TheUnreveal) is this for the [[TrilogyCreep Morning Star Trilogy]], published eight years later to mixed reviews.
* TalkingToThemself: Well, writing to himself, if you go by the theory that Sabine was never real, and was just an imaginary friend Griffin made up.
* TheUnreveal: [[spoiler: We never find out for sure whether Sabine and Griffin managed to meet in Alexandria. However, the final letter is adressed to a doctor in Kenya, from Sabine (but using Griffin's seal, and the middle initial "M") and repeatedly uses the word "we", so it can be assumed that they are together. Or that Griffin has just gone completely insane.]]
* WalkingTheEarth: Griffin spends pretty much all of ''Sabine's Notebook'' doing this, while Sabine stays at his house in London.
