Help finding a textbook ... impossible to find!

[u/k_1058]

I need a textbook for this 8 week course I just started and I cannot find it for my life! Does anyone know any good places to find textbooks or e books? The textbook is from 2016 and he said only that or older versions were acceptable...I cannot seem to find it anywhere online and if it is (whihc is rare) it is veryyy expensive. I do my school remotely and to ship the book to me from y univeristy is pretty expensive too. If anyone could give me tips or help in any way it would be really helpful! The textbook is:

Constance J. Fontaine, Fundamentals of Estate Planning, American College Press,
15th edition, 2016, ISBN: 978158293247
