We buy ebooks from many different vendors and they all have their own timeout period. It is usually somewhere around 15 minutes. Can you let us know which book it was and we can check. There is usually a logout button that you can use to close it when you are done.
|Monday - Friday||8 a.m. - 8 p.m.|
