Tying The Knot Maggie Casper Book four in the O'Malley Wild series. Those Wild O'Malley boys are at it again. From rough and rugged rancher Hayden, to larger than life pub owner Sean, all the way down to the baby of the family, polished and shined Zane, the only thing these brothers have in common besides wicked hazel eyes and an eagerness to love their women is a wedding. At the culmination of the O'Malley Wild series, join the O'Malley boys on their triple wedding day at the Big O Ranch...and more enjoyably, their individual wedding nights. Nothing is too wild for an O'Malley. Note: The first three stories should be read before reading book four.
