A Game of Thrones LCG : A Song of Summer

From the publisher's website:

The smallfolk say that the last year of summer is always the hottest. It is not so, yet ofttimes it feels that way, does it not? On days like this, I envy you northerners your summer snows.” 

—Grand Maester Pycelle

A Song of Summer is the first monthly installment of 40 fixed cards for the A Time of Ravens expansion to the A Game of Thrones card game, based on George R.R. Martin’s bestselling A Song of Ice and Fire saga. It contains 20 different never-before-seen cards designed to augment existing decks and add variety to the A Game of Thrones metagame.

This is not a stand-alone deck; an A Game of Thrones: The Card Game core set is required to play.
