By default, your Rental Shelf will send selections based on your priority, then on availability. If your top selection isn't available, the Rental Shelf will move down your list to the next available selection.
However, if you would like to receive your titles in a particular order (i.e. books in a series), you can use the Lock feature on your Rental Shelf. To use this feature, click the 'lock' icon beside the 2nd title in the series - this will bring up the Set Dependency box. In here, use the drop down list and select the 1st title in the series. Click 'Lock'. The 2nd title will now be sent only after the 1st title has been finished. Repeat for any remaining books in the series.
