Book for coastal foraging

[CheeseMonster]

Apologies if this has been posted before, I have searched for 30 minutes on the forum and not been able to find a thread specifically about this.

Can anyone recommend a book for coastal foraging?

I have been looking at this:
http://www.amazon.co.uk/Edible-Seashore-River-Cottage-Handbook/dp/0747595313/

But it's not quite a handbook, whilst sounding entertaining I want something I can take to the coast and use as a quick reference book.

Collin's Gem do a book but there is no mention of specifying whether things are edible on there.

Thank you for your time.

Thanks buddy

I had come across a book of his online but was put off by the synopsis/review. I will give him another look.
