Earlier in the week, Game of Thrones fans were treated to the first four episode titles of season 4. Now HBO has released the official episode synopses as well as a full season summary.

Readers of George R.R. Martin's A Song of Ice and Fire series probably already know what to expect from the new season based on the latter half of the third book, A Storm of Swords. For those that don't, HBO is willing to drop a few hints.

The summary suggests that while the Lannisters still maintain hold over the Iron Throne, there will be many new threats to deal with in the new season. Stannis Baratheon is rebuilding an army in Dragonstone. Meanwhile, Oberyn Martell, the "Red Viper of Dorne" shows up at King's Landing to attend Joeffrey and Margery's wedding. The Night's Watch will have to deal with Mance Rayder's army of wildings, as well as the undead White Walkers. Finally, Daenerys Targaryen makes her move on Mereen, the largest of the slaver cities, and eventually the Iron Throne itself.

HBO also provided descriptions for the first four episodes.

In episode one, "The Two Swords," "Tyrion (Peter Dinklage) welcomes a guest to King's Landing. At Castle Black, Jon Snow (Kit Harington) finds himself unwelcome. Dany (Emilia Clarke) is pointed to Meereen, the mother of all slave cities. Arya (Maisie Williams) runs into an old friend."

The second episode, "The Lion and the Rose," was assumed to hint at the marriage between Joeffrey Lannister and Margery Tyrell. According to HBO, "Tyrion lends Jaime (Nikolaj Coster-Waldau) a hand. Joffrey (Jack Gleeson) and Margaery (Natalie Dormer) host a breakfast. At Dragonstone, Stannis (Stephen Dillane) loses patience with Davos (Liam Cunningham). Ramsay (Iwan Rheon) finds a purpose for his pet. North of the Wall, Bran (Isaac Hempstead Wright) sees where they must go."

The third episode, "Breaker of Chains," will feature Daenerys as expected. "Tyrion ponders his options. Tywin (Charles Dance) extends an olive branch. Sam (John Bradley) realizes Castle Black isn't safe, and Jon proposes a bold plan. The Hound (Rory McCann) teaches Arya the way things are. Dany chooses her champion."

Finally, in "Oathkeeper," "Dany balances justice and mercy. Jaime tasks Brienne (Gwendoline Christie) with his honor. Jon secures volunteers while Bran, Jojen (Thomas Brodie-Sangster), Meera (Ellie Kendrick) and Hodor (Kristian Nairn) stumble on shelter."

Season 4 of Game of Thrones will air on April 6. Excited? Let us know in the comment section below.
