You may think this is another nothing book, there are some pictures of the author's children holding up finds from the beach. But this is certainly something, even for a marine biologist, even for someone with a keen interest in nature (not just a casual autumn watch watcher). A wealth of information and useful tips for identification, plenty of interesting nuggets of history and folklore. Not only are seaweeds and shells and eggcases covered, but human waste too. Odd shaped plastic contraptions common on beaches can be identified as disposable water-purification units found on boats, all sorts of common objects are covered. Truly a useful book if you want to know what you have just found on the beach, and an interesting book to flip through at home.
