Her betrothal to Trystane Martell, meant to seal a peace between the crown and Dorne
A princess sent to Dorne as a marriage prize and a hostage in the same gesture, who found in exile more kindness than King's Landing had ever offered her.
A Princess Sent South
Born in 290 AC, Cersei and Jaime's only daughter — believed, like her brothers, to be Robert's — Myrcella was by most accounts the sweetest-tempered of Cersei's children, sheltered from much though not all of Joffrey's cruelty at court. She was betrothed to Trystane Martell of Dorne as part of Tyrion's peace-brokering during his Handship, and sent south under the guard of Ser Arys Oakheart of the Kingsguard — a departure that, as it happened, pulled her clear of King's Landing just before the worst of the war reached the capital, arguably the luckiest thing to happen to any of Cersei's children.
A Dornish Education
Myrcella thrived in Dorne rather more than she ever had in King's Landing, growing genuinely fond of Trystane and of Dorne's more relaxed customs, and mastered cyvasse well enough to beat her betrothed at his own favored game — small, deliberate details the text uses to sketch a happier girl than the one who sailed south.
That peace was shattered when Ser Gerold Dayne, acting on motives of his own, ambushed her escort and cut away part of her ear before Areo Hotah and Trystane's household guard drove him off, at a cost to her escort that the maester's ledger records but does not dwell on. As the published books end, Myrcella is being sent back toward King's Landing by ship, her wound healing and her future entirely unsettled.

Reading the character
Myrcella's story is a quiet rebuttal to the idea that a hostage's life must be a diminished one: sent south chiefly as a marriage prize and a guarantee of Dornish good behavior, she finds in Dorne more warmth and freedom than King's Landing ever offered her — a detail the text uses to needle at just how joyless the Lannister court really is by comparison.
Her time in Dorne is also a reminder of how little control any of the war's highborn children have over their own safety, however far from the fighting they're sent — a vulnerability that Dorne's own factional tensions bring home more than once.
The arc of Myrcella Baratheon
This carries the character’s road through the published novels. Read on only if you do not fear to know.
Ser Arys Oakheart, the Kingsguard knight assigned to guard her, dies defending her in the same ambush that costs her part of an ear. What Dorne's court truly intended for Myrcella, and how close she came to being used as more than a hostage, is a question the text raises through several conflicting Dornish voices and never fully settles.
These partings name deaths, endings, and roads not yet ridden in the books. Unveil them only if both roads are known to you — or if you do not fear to know.
Legacy
Myrcella's ordeal in Dorne cost her a piece of her ear and very nearly her life, and yet the record suggests she left Dorne more herself than King's Landing had ever allowed her to be.
