Chasing Time by Elena Lawson

I don’t know what I expected to happen when I swallowed the little golden pill, but passing out and waking up in another century was not a side-effect I was prepared for.
Neither was being hauled out of the Thames sputtering and shivering by a man with only half a face and being taken back to his home. Or finding that he lived with three other equally mysterious and gorgeous men.
They weren’t exactly quick to welcome me, and something about them isn’t right. Not entirely… human.
I was on the cusp of figuring it out when I woke up. Back in the present. At first, I chalked it all up to a bad trip, but I’ve never been good at letting sleeping dogs lie.
In my hunt for answers and the dealer who can get me more of the strange drug, I’ll find the truth. Whether I’m ready to hear it or not. And then there will be no turning back.
