Narrative:
VFR/night time conditions. I just took the local control position; aircraft Y was on a visual approach to runway 16. Aircraft X was in the runway 16 run-up pad. Aircraft Y checks in; I clear aircraft Y to land runway 16. Shortly after aircraft X calls I'm at runway 16 ready to go. I instructed aircraft X to 'taxi up to and hold short runway 16' and aircraft X read back 'taxi up and hold short.' after reviewing the tapes aircraft X did leave out the 'runway 16' on the hold short read back. A few seconds after aircraft X says 'we are lining up and waiting'. I looked out the window to find aircraft X and I wasn't certain of the position of aircraft X with all the lights at the approach end. I asked the pilot of her position and determined that she was on the runway and I immediately send aircraft Y around who was just inside a half mile final. The pilot of aircraft X called the next morning. She explained that she was a student pilot and she misunderstood the instruction I gave her 'taxi up to and hold short runway 16' since she was already holding short of the runway. I gave the instruction to taxi up to and hold short of runway 16 because aircraft X appeared to be in the run-up pad.factors:1) misunderstanding of my instructions led to the event.2) I missed the runway 16 in the read back.3) still fairly new to the facility and I couldn't determine where aircraft X was.stick to simple instructions. 'Hold short of runway 16.'
