The latest by Tracy Cooper Posey "Time and Tyra Again" from her Kiss Across Time Series

A wonderful short story explaining what happens to two time traveling vampires when they meet as planned one hundred years later. They both learn more about their time travels and the consequences actions or non-actions can take; how they are linked. One needs answers of a love he cannot remember. The other gets an inkling of how traveling from the future to the past actually just might be what keeps the future as it should be. This story is a perfect addition to the "Kiss Across Time" series; giving us a few more details to better understand these great characters in their current lives. I absolutely love this series, you never know what the author is going to give us around that proverbial corner, but you know it will be filled with magnificent surprises.
