Oh, thanks for the help Kelpie and everyone. The agent's site asked for 'a full synopsis or outline" but they also do non-fiction. In her letter she asked for a full synopsis, specifically. I have a tight concise one page synopsis that has all the major twists and such but I'm wondering since I sent it to her already if she's wanting something longer or just a hardcopy of the one I sent already. Here, let me post the one I sent to them and let me know if it's fine the way it is or if I should expand it further.:
Intro is here.
At age 25, ANDREA REGAL and her twin, ELISE are accomplished Egyptologists. Andrea has searched her entire life for the tomb of the Pharaoh KHUFU, Builder of the Great Pyramid, but it has eluded her. When she finds an ancient prophecy inside the Queen’s Chamber, she releases a preordained chain of events that leads her to the tomb and the Talismans of Time.
Andrea vanishes and Elise begins to experience hallucinations. While her family searches modern day Cairo, the Ankh of Time transports Andrea to the court of the great pharaoh himself. She learns she is destined to become the Sun God RA’s Warrior and save the world from APEP, The Destroyer who wants to swallow Ra and unleash his torturous abyss upon the earth.
Khufu’s infatuation with the young warrior turns to love--a love she cannot deny or accept. As the ancient gods teach her the art of magic and war, her family seeks help from an occult master named MAJEED. After Andrea travels to the Egyptian underworld and frees herself of the evil she harbors within, she agrees to marry the king. Deception lies within and BASTET gambles with the future for personal revenge. A charm sent to Elise allows her to touch Andrea and return her to the present.
Injured, Andrea receives help from the gods to heal herself because during her extended absence Khufu has succumbed to the Dark Lord's spell of lunacy. Upon her homecoming, Andrea's husband kills her with a magical dagger which sends her soul to Apep's volcanic domain. Her training continues after ADEL, her dig supervisor and family friend, is murdered protecting Elise as she seeks the Ankh of Life, which recovers her sister's soul from death. Apep gains his freedom and his minions descend on the earth. The twins must merge souls into one body to defeat the Dark God. As Apep’s blade descends upon Andrea, she and Elise unite and together they bind Apep to the underworld.
Khufu and his warrior bride live out the remainder of their lives until he dies of old age. The gods have pity on Andrea. They risk their own immortality to return her to her proper place by taking a potion, which freezes them all in time. With a broken heart, Andrea is reawakened by her family and she attempts to resume a normal life. A year later her father, MARK, sponsors an exhibit. Mark introduces Andrea to a benefactor with an unsettling affection for her. During their first dance, he reveals himself not as a stranger, but as Khufu.
All the major twists are in there including the ending which paves the way for book two (something I also mentioned in the query).
I sent a one page synopsis but am thinking she wants a chapter by chapter summary. Should I write a chapter by chapter summary? I have three days until snail mail runs again.
