Aion by Ludovic Rio

Captain Lexi Neel thought she'd sacrificed years of life with her daughter when she left Earth on a decades-long journey through the depths of space. But when a distress signal takes her out of hypersleep years ahead of schedule, she finds herself on the mysterious moon Aion, home to exotic wildlife and a research station dedicated to study of the moon's "particularities." It might mean a chance to start over as if she never left... As Lexi is about to learn, time is an experience.
