Dreaming Damage — Marie Treanor

Rykov has found a secret world unknown to dream tourists, where he can research the history of science and seduce Persephone, a beautiful and gifted student who turns out to be the sweetest of lovers.

Only London in 1809 was never really like this. And when NightDreamz client Kramer is trapped there, Rykov realizes the dreamers are damaging not only individuals but the fabric of time itself. And yet if he risks the ire of NightDreamz' powerful investors to close it all down, he'd lose Persephone too.
