Question

I HOPE I did not post this in the wrong spot. If I did so sorry and please point me to the right area Please and Thank you.

When I open The calibre ebook reader program, it takes me to a page for me to select book. What I wanna do is When I open Calibre Ebook Reader it takes me Right to the book I was reading.

Is this possible, If so what am I missing.......my guess if I am missing something its pretty simple. Thank you.
