Hello and thanks to anyone ahead of time for your help. I dont remember much about this book, but it was one that really got me started reading in the first place so I'd like to try and re-read it. the main character i believe was a carpenter or something along those lines before he started practicing magic, several times he reflects on his old life during the book. i think he might have been kicked out of his wizard schooling. i remember he thought of a women he wasnt traveling with but had in the recent past(which makes me think this may have been a series). i believe in the start of the book he is traveling alone but is quickly joined by at least one character who is a swordsman or warrior. at the end of the book they fight in an old tower (abandoned and/ordamaged) against beings who can materialize out of nowhere. those last two things i am a bit unsure of. What i am most sure of is the fact the magic system has a quirk where every spell the main character casts drains his person and i believe he even passes out or comes close a couple of times (might also corrupt, but not sure). another thing i remember is the author actually wrote in parts of the spells as the characters dialogue when he would cast a spell instead of always writing "he cast the spell for...". I also remember the main characters main offensive spells was lighting bolts (cast it many times). Sorry its all so vague, i wrote everything i could think of in hopes that many vague things would add up to something. Thanks!! Also should say i read this book over ten years ago, and i believe in paper back. The cover was rather plain with a short title (one or two words).
