When special operations Major Andrew Grayson and NACS Washington disappear without a trace during a clandestine mission to the Capella system, his wife, Lieutenant Colonel Halley, is left reeling. With Andrew's whereabouts unknown, she settles in for a long and agonizing wait as their lives together are put on hold. This is Halley's personal journal, started shortly after Andrew's disappearance. It chronicles the highs and lows of her life without him as the silence of his absence stretches out over months and then years. The journal that begins as a reluctantly obeyed order from her military therapist becomes Halley's sounding board for her joys and fears, a record of all the big and small events that shape her life as she waits for Andrew to come home. Author's Echoes of Silence is told in epistolary format. This is a collection of Halley's diary entries that cover the timespan of the Frontlines novels Orders of Battle and Centers of Gravity. To understand the references in this novella and to avoid spoilers, it's recommended to have read Orders of Battle (Frontlines #7) and Centers of Gravity (Frontlines #8) first.
