Bramble Burn

It had been thirty years since the Convergence, when the dimensions aligned and combined Earth and the world of Gwyllon, known in human mythology as "Underhill". Elven castles and ancient ruins sprouted in vacant lots, on major highways, sometimes merging with existing buildings, twisting into completely new structures. Roads and rail systems reformed, and after the rioting, starvation and death, agriculture finally sorted itself and food began to flow. A new government formed of elves and men had arisen, a society of human tech and elven magic. Cell phones and frost giants, race cars and elven steeds, dungeons and dragons…
And everywhere, monsters.
Tree mage Juniper was twenty-three, a child of the new generation. When she found a source of magic buried in an abandoned park, she made a deal with the city. If she can stabilize the park's wild magic, she'll own it…if she can survive.
Now she has to clear out magic spawned monsters, deal with a werewolf suitor and survive her bloodthirsty dragon uncle. She's going to have to dig deep to subdue Bramble Burn Park.
Contains no graphic love scenes. Expect reasonable amounts of gore as monster heads explode and plenty of action.
