Mark Anthony was one of the first fantasy writers I discovered and I've always wished this author would release more books
Grace is a Dr and she gets dragged into a strange world after witnessing a man with an iron heart attack and kill people in her hospital. Travis owns a pub and his friend gifts him with control of Runes before he also gets dragged into the same strange world as Grace. Individually these two meet folks that help them adjust to this strange place and the almost medieval way of life. However, there is magic and strange creatures that also exist and a Dark ruler is trying to escape a prison to bring about a terrible winter and the end of normal existance. Grace learns she is gifted with a touch of magic too and she uses her influence with a local King to rally other leaders against the coming threat. Travis has become one of a dieing breed of Rune Speakers and his gift is dangerous with him being so inexperienced. Eventually the pair meet up and band together to stand against the Pale King's minions.
