Okay I won't say there is no point! Just take it as read. So if you must...
The texts that i have used most of the time this year are, the Marieb for Anatomy and Gray's Anatomy for Students, as a backup. I bought Gray's and have borrowed Marieb from the university library. My copy was a weekly loan! so the loan has been renewed about 28 times this year. If you use a library version try and get it on a monthly loan version. That covers most of the Anatomy though you may find that your lecturers used a different one to prepare their lectures and it might be worth seeing what they recommend.
I also like the Anatomy Colouring Book by Kapit. You can get that on Amazon for about £9.99 which is half the price from Waterstones. You can also get a Physiology version but i haven't seen it so can't recommend it.
For general information I would suggest the Physiotherapist Pocket Book, and Tidy's Physiotherapy. A Dictionary of Physiotherapy is also handy for browsing through.
You could also try looking at some specific texts dealing with Neuro, Musculo-skeletal and Respiratory.
You'll probably be doing some study skills as part of your course so a read of a book dealing with that is a good idea. You'll also be doing a lot! about Evidence Based Practice and every man and his dog have written about that. You could try Practical Evidence-Based Physiotherapy by R Herbert and his mates.
I understand why you want to read ahead, but you will be immersed in Physio for the next 9 months, until next summer, and frankly you could get a bit jaded if you don't give yourself some breathing space this summer and wind down a bit.
I would also recommend not buying anything until you see what is available in the uni library. Some books you may only use a couple of times, others you may find yourself glued to. But you won't know until you need them. I would suggest buying the colouring book and search Amazon for the others to get their ISBN numbers. Once you got the ISBN numbers ask your local library to obtain copies for you. Then in September when you have your book list you can decide what to buy and what to borrow from the library.
Enjoy.
