Cat Summer. The Cat Seasons Tetralogy

Lise has a special destiny: to help a clowder of sentient cats save the world from an evil older than history itself. It is a terrible battle, but Lise and her comrades prevail, putting an end to war, poverty, ignorance and want. Or did they?             A century later, it comes clear that something has been lost. The new civilization produces no artists, no musicians, no scientists, no philosophers.
Apathy has taken hold. Lise, now at the end of her life, must join her cat-friends once more to restore the Spark of the Human Spirit, but the goal cannot be reached without sacrifice.
