I read Albright's book after visiting Prague and Terezin and also highly recommend it. I also read a novel https://www.alysonrichman.com/the-lost-wife that was set, in part, in Terezin. Also, do some research on the art, literature and music that was created at Terezin. Terezin was a priority for me when visiting Prague because our son had performed in Bundibar, a children's opera that was performed over 50 times at Terezin. One of the original cast members from the Terezin performances gave an introduction and it was extremely moving. Our daughter, when she was in choir, sang settings of poems written by children at Terezin. You will find a lot of information about Brundibar if you do a google search. Having an appreciation of the talents and contributions of Terezin prisoners made our visit much more meaningful.
