Anne McCaffrey first created a universe where telepathy and psychokinesis exist in her Pegasus books, and this novel is the first of a five-book series set in that same universe. The series is usually referred to as The Tower and the Hive Series. The Rowan is a very talented orphan whose talent "erupts" when the rest of her community is wiped out in a landslide. She is called The Rowan because that was the name of the mining company where her family worked, and since no one alive knows what name she was given, they just call her The Rowan. Then she gets a telepathic message from a remote colony that they are being attacked by aliens.
I listened to this as an audio book.
