An imaginative thriller about first contact, survival, and the nature of reality.
When an intelligent alien spaceship arrives in our solar system, no one on Earth notices. Not until brilliant hacker Mazie G stumbles across a surprisingly skillful intruder in her employer's computer systems, and sets to work uncovering their identity.

What she discovers takes her breath away. When she informs her employer, she finds herself ensnared in a web of secrets that could threaten the future of humanity. In a race against time, she tries to understand what the alien intruder wants before events spin out of control.

If you enjoy movies like Contact and Arrival, or stories such as Arthur C. Clarke's Rama series, then Sojourner is the book for you.
