We review a motion for continuance under an abuse of discretion standard and will only reverse if injustice will result to the party desiring the continuance. In Interest of C.W., 554 N.W.2d 279, 281 (Iowa App. 1996). Denial of a motion to continue must be unreasonable under the circumstances before we will reverse. Michael v. Harrison County Rural Elec.
