I listen to audiobooks because they enable me to expand my reading. When traveling or exercising they are companions; I often listen during the night when sleep is elusive -- excellent soporifics, setting a timer provides fine tuning and it's simple to return to an earlier section or chapter. I subscribe to audible.com, which provides plans with lower cost/book. Best audiobook for me has been The Prince of Tides by Pat Conroy; best series is Patrick O'Brian's stories of Captain Jack Aubrey's command of British naval vessels during the days of sails and sea battles. Captain Aubrey's companion on these adventures is ship's surgeon Steven Maturin, an accomplished physician who also plays music with Jack. Superb adventures with sharp character portrayals.
