Metastable: Book One of Two

By Jern Tonkoi

Carter Brent knows how to keep a system stable.

Stay immaculate. Stay useful. Stay ahead of every variable.

Tan Naiya is the variable he has never been able to solve.

They have been friends since school, entangled through a year neither of them escaped cleanly. Now in a London physics department, Carter watches Tan live with an ease Carter cannot forgive and cannot stop wanting. When Tan realises how much Carter has controlled, hidden, and kept, he does not walk away.

He decides Carter owes him.

A year, to start.

What follows is not a sweet campus awakening. It is late nights in the lab, walks by the Thames, a Soho bar with a sauna underneath it, and two men testing whether desire can become care before it becomes another way to hurt each other.

Metastable is Book One of Two in Carter and Tan's romance arc: explicit, psychologically intense contemporary M/M romance with a strong HFN ending. Carter and Tan's hard-won HEA comes in Metastable: Book Two of Two.
