What was that Celtic book of prayers?

A couple of years ago, at Desert Trek, for evening devotions you read from a (Celtic?) book of prayers (devotions?). Do you remember the book I might be referring to? Could you tell me the title and author (or enough identifying information to perhaps track it down and buy a copy)?

Yes, My wife has loaned ours out i think, it is Celtic daily prayer.

Here is a link to the prayers on the web.  very accessible, through the links to the Daily Office on the RHS of the page.

God, please help this brother

and sister, with their bairns,

to serve as a mother

serves loved ones with her hands,

and lips. With warnings - "Burn-ey!"

May they, as they build cairns

of stones to mark the journey

still listen to God's plans

and thus become his prophet

who, like Jeremiah said,

speak God's Word (don't cough it),

and folk hear, and understand,

and turn from their wicked ways

to their God who saved them

that's what Jeremiah says

Oh, make it true (again)!
