welcome to GoY.
there are lots of plants suitable for full shade.
if you scroll to the bottom of this page you will find the alphabet. click on S and then it will take you to a selection of which shade is an option.

I have lots of shade and there are some lovely plants eg
Pachysandra, epimedium, many ferns to name but a few.
how big an area have you got?

I've got a very small patch in shade and I grow a couple of huge hostas, two clematis, Solomon's seal, Iris, Pulmonaria, a rose, Lily of the valley, a Daphne and more and they are doing really well.

There are also several perennial geraniums and very surprisingly crocosmia is doing well in shade here. If you have room Mahonia - you could try the new Sweet Caress if its sheltered from the wind.
