All Time (All Time, #1) by Mack Leonard

In the year 2397, Miranda Hawking is living with her parents at the Hawking Refuge for Troubled Intelligences, a “retirement” sanctuary for used-up channelers. These synthetic beings, in their prime, had interfaced with the most powerful artificial intelligences that guided the universe and then interpreted their thoughts in a way humans could understand.

Many of the channelers eventually succumbed to the pressures of their responsibilities and, if they were lucky, ended up at the Refuge cared for by Miranda and her loving parents but forbidden from ever contacting their master intelligence again. One such resident is the mysterious (in Miranda’s teenage-crush eyes), Brightside, who had been channeler to the great master intelligence, OMNIUM.

When the Information Police come knocking, Miranda discovers not everything at the sanctuary is as tranquil and mundane as she’d thought. Not only has Brightside been in communication with his old master but her mother is involved in something with him as well.

Helping Brightside to escape, Miranda attempts to find out what is going on. She joins Brightside onboard a subspace ferry and next finds herself face to face with Altrius Prime, the highest political authority in the solar system (and the oldest one), who she prevents from committing suicide by making an unauthorized time jump.

As she disrupts his plans, Miranda herself makes the jump and ends up on a wooded mountainside in the year 1058. No sooner has she gathered her senses from the jump when she is attacked by a warrior from the invading horde known as the Holders of the Chain.

Her rescuer is an apprenticed painter, Friskin York, who along with his master had been on the mountain to capture the magnificent vista. Miranda slowly falls for Friskin as the three travel to find a place of safety from the invasion and search for her parents who tried to follow her during her accidental time jump.

All Time is an engrossing story with great characters and vivid world-building not only of a far future but of the past. There are numerous twists and turns along the way as Miranda tries to understand her new reality and she doesn’t always find herself welcome. There are unresolved issues in this first book that I hope to pursue in subsequent books in the series.

I highly recommend this book for readers that like time travel stories and grand adventures.
