The budding romance is put to the test when Roland decides to enlist to fight as World War I breaks out. Vera herself is not left unscathed as she's forced to delay getting her degree in order to work as a V.A.D. nurse.

“Testament of Youth” was the first of three memoirs Vera Brittain published during her lifetime. It was followed by “Testament of Friendship” and “Testament of Experience.”
