Everyone mourns the loss of a friend in their own way. And while William Shatner may have missed the February funeral of his longtime friend and colleague Leonard Nimoy, he has found another way to honor the great Vulcan.

Shatner is planning to share his memories and thoughts about Nimoy in a new book.

"I had a brother, whose life arc was so much like mine that we understood each other completely," Shatner recently told The Guardian. "Our age, our birth, the same types of problems in our marriages. Our careers arced in the same manner."

Shatner and Nimoy first worked closely together on the original "Star Trek" as Kirk and Spock, although reports were that the relationship between the two were rocky. Yet, after the show's cancellation, and living in the shadow of the franchise afterward, the two actually became close.

The two have a lot in common, as well. They were literally born just four days apart, and a little more than 300 miles from each other. Both came from strong Jewish families, and both witnessed their star power peak at about the same time.

"We had a great deal in common, Leonard and I," Shatner said. "And thusly, we were able to understand each other. I've lost a dear friend."

Shatner has written a number of books, including six in the non-fiction category. Nearly all of them have been bestsellers, and have focused on his career in Star Trek. He also co-wrote a number of fictional books, including the TekWar and Quest for Tomorrow series.

Shatner didn't reveal when he would start working on a book, or when fans might be able to see it. The actor just did a mass digital release of his latest documentary, "Chaos on the Bridge" — focused on the first three years of "Star Trek: The Next Generation" — this weekend.
