Lost Ocean is a book by Johanna Basford and is full of underwater adventures with many sea creatures, plants and other items to discover and colour. There are lots of pictures with small details in this book and lots of people enjoy that as they can get really lost in a picture. You will need to use gel pens or very sharp pencils to complete a lot of them though! There is a treasure hunt in this book too where you are tasked with finding things such as gold bars, jewels and other sea treasures.
I have completed a copy of the book and have filmed a flip through which you can view below:
