Release Message:  Adrian receives a package from his father which contains devices that have the ability to take you anywhere at any point in time... Written by Jack McDevitt.

Description:  About time travel and the consequences it can cause. The novel is a reworking of McDevitt's 1996 novella of the same title, which in 1997 was nominated for both a Hugo Award and a Nebula Award. McDevitt rewrote the story because he was inspired to work with time travel once again. After his father Michael Shelborne mysteriously disappears, Adrian "Shel" Shelborne receives a package from his father with instructions to follow if something were to happen to him. Inside the package there are four devices that the note instructs him to destroy. After toying with the device a little, Shel discovers that the devices have the ability to take you anywhere at any point in time...
