'Invasion Rabaul' is a gut-wrenching account of courage and sacrifice, folly and disaster, as seen through the eyes of the Allied defenders who survived the Japanese assault on Britain during the opening days of World War II.

In this never-before-seen memoir, Bergen-Belsen survivor Hannah Pick-Goslar shares incredibly powerful words on the final untold portrait of her childhood friend, Anne Frank. The inspiring and heartbreaking true story of two best friends torn apart and reunited against all odds.

When Hannah Pick-Goslar's family fled Nazi Germany for Amsterdam, she struck up a close friendship with her next-door neighbour; precocious, outspoken and fun-loving Anne Frank. Hannah instantly warmed to happy-go-lucky Anne and for seven blissful years, the inseparable pair navigated school, boys and coming of age in Amsterdam's Rivierenbuurt neighbourhood. But in 1942, life quickly changed for the thirteen-year-old girls.

The Nazi occupation of Amsterdam meant the friends were separated without warning. Hannah called on Anne, but there was no trace of her friend or her precious diary. Hannah was tormented over the fate of Anne, wondering if, by some stroke of fortune she had escaped danger and was alive and well elsewhere. It wasn't until Hannah reached her darkest point, imprisoned with her family in Bergen-Belsen concentration camp, that she had an astonishing chance reunion with Anne. Desperate to save her friend who was weak and struggling to survive, Hannah risked everything to toss packages filled with food and clothes over a barbed-wire fence. Hannah only learned of Anne's death after her liberation, when Otto Frank came to visit her in hospital. From that day, Otto became a second father to Hannah, making sure that she was always looked after.

In this groundbreaking memoir, Hannah Pick-Goslar shares an intimate portrait of Anne Frank, the young Jewish diarist who has captured the hearts of millions of readers around the world.
