Introduction
The Enterprise is sent careening through time by a chance astronomical phenomenon. When the crew comes to, they find themselves in a precarious orbit around Earth of the 1960s. How will they avoid detection by the powers of the day, inadvertently changing the past, and how indeed will they return to their own time?
Look out for that solar flare!
