The cousins, Kevin McClure and Lou Aguilar, were born mentally linked, as were their grandfathers Stuart and Samuel McClure, but when they started school, their oddness had set them apart. Kevin was easy with their link, but because Lou wanted to be "just like everybody else," Kevin taught him to build walls, and their link was broken. Now, as an adult, Lou realizes that he had thrown away something miraculous, and Kevin wants to help him reconnect. But Kevin and Molly are married, and if the link between Lou and Kevin is reestablished, therein lies the problem: how do two people with such a mental connection deal with personal relationships?

Connections explores that journey and delves into a traumatic episode in the young men's past, which, because of the no secrets rule, must be shared with Molly, the woman they both love. Together the three face fearsome problems and solve a long-standing mystery.

The LINKED series continues with Book Five: Family Secrets and Book Six: Grayhorse.
