All Our Yesterdays

Marina lives a privileged life in Washington D.C. with access to advanced technology and a close circle of friends. When a tragic event disrupts her world, she becomes entangled in a complex situation involving time travel and the fate of those she cares about. Em is imprisoned in a harsh facility where she faces regular interrogation. She discovers documents that reveal information about time travel technology and realizes she must attempt a dangerous escape to prevent catastrophic events from occurring. The narrative alternates between Marina and Em's perspectives as their stories intersect across different timelines. Both characters must make choices that will impact not only their own lives but potentially the course of history itself. At its core, this science fiction thriller explores questions about identity, the price of progress, and whether the end can ever justify the means. The story challenges assumptions about destiny versus free will while examining how time and circumstance shape who people become.

🕰️ Both main characters - Em and Marina - are different versions of the same person, separated by only four years but living drastically different lives. 📚 The title "All Our Yesterdays" comes from Shakespeare's Macbeth, specifically the famous "Tomorrow and tomorrow and tomorrow" soliloquy. 🔬 The time travel machine in the book, nicknamed "Cassandra," was inspired by the ancient Greek mythological figure Cassandra, who could see the future but was cursed so that no one would believe her predictions. ✍️ Author Cristin Terrill wrote the entire first draft of the novel during National Novel Writing Month (NaNoWriMo). 🎯 The book was originally planned as part of a duology, but the sequel was ultimately cancelled, making it a standalone novel despite some unresolved plot threads.
