A Soul to Guide (Duskwalker Brides, #4) by Opal Reyne

All Raewyn ever wanted was to go home.

After accidentally creating a portal to another realm, Raewyn finds herself trapped in a world she's struggling to navigate. Desperate to find those with magic who can help her, she sets out on a dangerous journey to another town.

Unfortunately, on her travels, she learns there are bigger and scarier monsters than the Demons she knows of - and one of them won't let her get away.

All Merikh ever wanted was to escape.

For a hundred and eighty years, Merikh has been hunting for a way off Earth. He doesn't care who he has to eat, kill, or maim to get what he wants. So, when his prey ends up being a lost Elf, he realises this is his opportunity.

She's prettier than any creature he's ever seen, and so damn perfect that it's impossible to resist her otherworldly lure.

But Merikh destroys everything he touches. Will he be able to overcome years of hatred and anger to allow himself to get close to her, or will he lose her in the process?
