It is possible that a book you have borrowed might be requested by someone else over vacation. However, in our experience, this rarely happens as most students are away from campus and not requesting physical items. All other copies of that book will also have to be on loan for yours to be recalled. Not only that but the system is set up so that books will not be recalled on closure days. In the unlikely event that you do receive an email saying that your book has been recalled, please use our freepost service so that you can post the item at no charge. The freepost address is: Freepost, University of Sussex Library.
