All Our Yesterdays is a strong follow-up to the ongoing story in this series. The flashbacks of Daniel and Nina’s past lives help to broaden the reader’s understanding of these characters and where they come from. The romance elements play a much more graphic and detailed part in continuation with the final chapter of Déjà Vu, lingering on the detailed exploration of Daniel and Nina’s physical relationship as they learn how to be a modern couple. Those in it strictly for the romance side of the story will find this a welcome addition to the narrative, but story wise, it does little to move the plot forward.

The action sequences usually begin mid-battle, causing the reader to have to catch up to what’s going on. But the mastermind behind these attacks makes for a rich and poignant plot twist along with their encounter with Nina’s homeland, forcing both Daniel and Nina to make tough decisions that will affect not only their relationship but also the potential fate of the world. While book one was about the characters coming to terms with who they are, book two is about reconciling their past selves with their present ones, concluding in a shocking decision that will shape their future.

Despite its shift in focus to a traditional romance angle, there are still some great plot developments, even better character developments, and a continued curiosity as to how it’s all going to end for Daniel and Nina.
