I went into this book expecting something like [b:Epilogue: A Novel|61223679|Epilogue A Novel|Lily Lashley|https://i.gr-assets.com/images/S/compressed.photo.goodreads.com/books/1654351499l/61223679.SX50.jpg|96523539], but despite being based on a similar (albeit different) premise, it is quite different. Epilogue is about showing how someone who went to an adult fantasy world, with real risks, politics, and a world similar to "earth but midevil and with magic". Every Heart a Doorway is completely different. The world contained within have substantial fundamental differences from our world, and are much more like fairy tale worlds than traditional fantasy. As such, the characters are not "fully mature people with PTSD in kids bodies", but "kids that had an adventure and were fundamentally changed by being somewhere so far separated from reality, who want nothing more than to go back".
