You are probably better with the monk/sorcerer for the defense bonuses of the monk (as a mage, you will spell fail more often in Armor). The monk makes very good use of touch attack spells, various buffing spells and area of effect spells. It is usually quite effective if you are going to go Red Dragon Disciple later in the game. There is a lot of close quarters fighting in Chapter 2 - so having the right mix of buffs and area of effect spells is important.
Arguably Wizard/Monk (See Palemaster/Wizard/Monk build) and Druid/Monk are better choices. The Druid/Monk has great potential as both classes rely on WIS - and druid spellbook contains a nice mixture of buffs and area of effect spells and the more combat oriented animal companions.
