Just Blow It Up — Kate Pavelle

Mother, grandmother, matriarch. In the 1970's communist Prague, Jarka's family yielded to her firm hand, with which she steered them through the militaristic and charged Cold War climate.
Except for her son-in-law, super-genius.
After an unexpected explosion rocked the house, Jarka decided upon her son-in-law's fate: disarmament, sudden and covert. She had to get rid of everything that went BOOM without getting caught, by him or by the authorities.
If you like historical fiction from behind the Iron Curtain, you'll love the riveting suspense of “Just Blow It Up,” another hilarious tale from the Cancelled Czech Files.
