Originally written anonymously, the author outed themselves here and here, so I figured it was fine to attach their name to the series in this rec.

These three fanfics tell a brutal and deeply characterized story of captivity and rape. Light's obsession combines along with Rem's stubbornness and ingenuity to lead to a situation of captivity for L. Nobody on the task force has any idea of where L is, while Light plays with L in various depraved ways.

Fanfics involving rape and captivity are common in the Death Note fandom, but this one stands out as very different from the vast majority of them.

Death Note rape-fics tend to go in one of two directions. Either they tend to be "fantasy rape" where the rape is unrealistic, clearly written for viewer titillation, and leads to the victim falling in love with the rapist, or they go the opposite direction and focus on rape as torture, with not much else in the story other than torture, torture and more torture, largely neglecting a plot and characterization.

This series manages to avoid both of those typical paths. L psychologically unravels under the strain of what he needs to do to survive, but he keeps a core of his real self alive, subversively hoping for a way out. A plot is here, in abundance, and so is lots of characterization, for L, Light, Misa and Rem.
