Project Azkaban by @Unfrozen Fox

This novel takes place in the mid 2020s with several of the Weasley-Potter clan's children starting their training as Unspeakables in the Department of Mysteries and specifically working on a project that has been in the works since just before the end of the Second Wizarding War in 1998. Gina's love of science fiction shows in this fic with only three chapters currently posted; discussions of ethics, morals, and basic scientific reasoning on whether project will work, how well it will work, and what it could possibly mean for those whom enter it for real in the future.

What's done quite excellently is that while we are following our trainees as they are beta-testing, so to speak, this project, we are also getting glimpses into the outside world and how their choices inside the project are affecting things on the outside. There are things happening that the project leaders and managers could not have foreseen, and, for our trainees, the possibilities of what could happen to them while inside the project could potentially be catastrophic, but we JUST. DON'T. KNOW. And that is what makes this such a compelling and intriguing story about ways for the Unspeakables to improve Azkaban prison.
