I know you know better than this,
but anyhow
Step though the program with a "legitimate" book
Step though the program with an "expired" book
find the fork
redirect the expired fork down the legitimate fork
In all honesty, kids stuff
As a book publisher, you have just spent god-knows how much money buying this DRM mechanism from someone, and it's cracked in hours
About the only way to realistically overcome this, is to require authorisation over the internet each time you open an e-book
which would be crap, and only annoy people
The "loaning" of things is a mechanism devised in the physical world of scarce products that cost money to reproduce
It doesn't translate (sanely) over into the digital world
