Open Ocean

The aquarium boss will be travelling to the USA soon, and finally it looks like Salt Cove is heading for quieter times. But then a mysterious lady shows up and steals something belonging to Ophelia. Why?

Once again, Ophelia and Bernard have to set out on a journey that is dangerous for them and for the monsters they are trying to protect.

Open Ocean is the third book in the Crypto series. The graphic novel is written and drawn by Hans Jørgen Sandnes, the man behind the illustrations for the popular Detective Agency no. 2 books.

“A magical underwater world...The design is consummate and professional.


“Hans Jørgen Sandnes (…) conjures great drama when, in words and pictures, he appeals to our fascination for unfamiliar underwater creatures that may need our help.”


“This is a highly promising, exciting and entertaining first instalment in a planned children’s series.”
