In the two years after the 1939 publication of Steinbeckâ€™s masterful The Grapes of Wrath, Steinbeck and his novel increasingly became the center of intense controversy and censorship. In search of a respite from the national stage, Steinbeck and his close friend, biologist Ed Ricketts, embarked on a month long marine specimen-collecting expedition in the Gulf of California, which resulted in their collaboration on the Sea of Cortez. In 1951, after Rickettsâ€™ death, Steinbeck reissued his narrative portion of the work in memory of his friend and the inspiration for Cannery Rowâ€™s Â“Docâ€ť. This exciting day-by-day account of their journey together is a rare blend of science, philosophy, and high-spirited adventure. This edition features an introduction by Richard Astro.
