Seeking beta reader for first half of fantasy novel

[Starmelace]

I'm looking for a beta reader to specifically look at continuation and plot for the first half of my fantasy novel Locomotive Incantation.

Basic plot:
Rowan has been trapped on a train "going nowhere" for fifteen years. Though unable to destroy her or her magic, her captors manage to contain her. In fifteen years, no one has ever been able to get on or off the train, until one day a girl from Portland, Oregon manages to get on the train, and is unable to get back off. Over the course of several days, more people wind up on the train, not all of them from the same time period. In order to free them all, Rowan must find a way to prove her magic can be used for selfless reasons, despite a past that she would rather leave behind her.

I am willing to trade but only certain types of novels and for roughly the same amount. If you're interested in reading and or trading, email me at laceyjs92@gmail.com or reply here. Thanks!
